Summary: Keywords: marine structures, dam on the slope, hydraulic stability, nose, blocks, mantle, formulas, parameters, slope density, radius, period, peralte, physical model testing, multidirectional waves The research developed aims at the analysis the stability of the nose of a dam on the slope. To this end, were carried out various tests in physical model in order to analyze the influence of various parameters, both structural and waves, in the stability of that part of the structure. Based on the experimental results obtained, has developed a formulation for the design of a nose cubic protected with concrete blocks, with a wide range of validity and an easy-to-use, which takes into account the main parameters estructuales (pensiente , density and radio nose) and wave (wave height and period), relating to the damage experienced by the structure. He also has analyzed the evolution of the damage, identifying varying degrees thereof, which may be helpful in setting the design criteria. Furthermore, we have been able to establish recommendations for testing in the laboratory and in the design of the prototype nose.

Summary: This work has been aimed at defining a key indicator for the functional evaluation of concrete pavements in container port terminals. The proposed indicator is calculated by a mathematical expression and allows classify the pavements of different areas of the terminal building on two aspects: the deterioration valuation and prioritization of areas. The valuation of deterioration quantifies their density in the pavements inspected while the prioritization classifies pavements according to the size of the terminal building and the use of the area in which they are located. The first part of the work has been to define how they are going to assess the deterioration of the pavement. To do so, has been selected a parameter for quantifying deterioration based on the study of damage more representative and its correlation with traffic and the age of the flooring studied. This parameter selected is the one used for the valuation of deterioration. The second part of the job has been to develop part of the index that performs the prioritization of the samples according to the size of the terminal building and the use of the area. It has valued the importance of the terminal through the parameter 'Index intensity of use' as defined in ROM 4.1-94. Furthermore, it has defined a procedure to assess the significance of the area of the terminal, taking into account their main use. To do so, a study has been made Delphi with a panel of experts formed by technicians port. As a result of this panel have obtained a procedure based on tables that can obtain an assessment of the significance of each area. The Delphi method also has led to the relative value that the technicians port attached to the importance of the terminal and the area where the samples are located. Once the indicator, has proposed a comprehensive methodology for the implementation of the proposed functional indicator. It has been necessary to establish two thresholds parameter for quantifying deterioration: warning and action. When the indicator reaching these values, action on the pavement will be recommended or mandatory respectively. These thresholds have been identified by a panel of experts.

Summary: This work will focus on studying the estabilidd one of the types of structures used in shipping engineering costs, which will call in a general way, dikes escollera rebasables and submerged and can be divided into two types according to their use: dykes with coronation near the middle level and the dikes or submerged structures very close to the fund. Call dikes escollera concoronación close to the average level (low crested structures LCS) those dams slope whose coronacións and located close to sea level meido dle (still water level-SWL). Therefore, these structures can be emerged, submerged or alternatively depending on the state of tide, but are characterized by being designed to allow the transfer of a significant amount of energy as a result of the overshoot. Formulations of stability, when one considers that the dam is large enough to disrupt the flow, are often based on the old técnia of dimensional analysis. The submerged dikes or structures very close to the fund are those whose height is small encomparación with the depth of water that must endure. The depth to which these structures are immersed is sufficient to assume that the rogura of olejae not affect the flow alrdedor this structure. This definition separates the dams with coronation near the middle level. The formulations of existing stability for such structures are based on models cuasi-empíricos, which are based on the assumption that damage will depend on various parameters adimensionales representing hydrodynamic forces acting on the parts. These techniques have been used traditionally assuming a profile velocity calculated with linear theory (Airy), which is not affected by the existence of this small structure of the fund. Today, the development of numerical wave channels based on the Navier Stokes equations has contributed to a growing awareness of genetic processes in detail wave interaction with porous structures. In particular the model MARIFÉ (Model Advanced Rans Interaction Flow Structure) is a development d ela University of Cantabria model COBRAS (COrnell BReaking wave And Structure) desarrolado initially by Lin and Liu (1998). The model MARIFÉ based on the equations VARANS (Volumen- Averaged Reynolds Averaged Navier Stokes) is the only two-dimensional in the literature can simulate turbulence within the porous media. Monitoring the superficielibre is done via the VOF method "Volume of Fluid (VOF), capable of representing chaotic configurations of the free surface which can have situaicones breakage of olejae. This tool has been used to model the flow in the trials of stability FEDER-Estabilidad conducted at the University of Cantabria in the year 2001. These tests were conducted in the field delproyecto ERDF "Study in prototype flow and stability protections escollera emissaries of submarines", which sweep francobordos desdes structures submerged until very structures emerged. The results have been used to understand the various types of damage in this type of structure, propose new design methodologies, in addition to improving existing ones.
