Abstract: Experimental investigations were mainly carried out to clarify the influence of the seabed proximity on hydrodynamic forces on a submarine piggyback pipeline under regular and irregular wave action. Nondimensional force ...

Abstract: Experiments on a large pipeline and a small pipeline in a piggyback configuration under regular and irregular waves are carried out. A comparison of the wave forces on the large pipeline and the small pipeline is made. The ...

Abstract: Robotic flat-end milling of complex surfaces offers advantages such as high flexibility and high machining efficiency. In the process of planning the toolpath based on the cutter contact path, the robot functional redundancy ...

Abstract: Accelerated distress of Portland cement concrete pavements (PCCP) over structures such as culverts, pipes, and tunnels beneath roadways is a common occurrence. In this article, finite element analysis is employed to analyze ...

Abstract: The effects of cement content and curing period on a new synthetic model ice, DUT-1, are reported. The cement (450#) contents were 10%, 11%, 12%, 13%, 14%, 15% and 16% by dry weight of ...

Abstract: In order to analyze the stress varieties in cement pavement slabs caused by load with the existence of base cracks, the influences of moduli, crack locations and quantities of semi-rigid base and lean concrete base, thickness ...

Abstract: The management of urban land development, as well as the conservation and optimization of agricultural land and urban green space, is crucial for sustainable urban development. China has experienced rapid urbanization and ...

Abstract: The numerical simulations of wave interactions with armor blocks on rubble-mound breakwaters will enable a stronger understanding of breakwater failure and therefore increased malfunction prevention. This paper presents a ...

Abstract: The harmonization of environmental protection with land use for socioeconomic development is one of the major challenges that most Chinese cities are facing in the rapid urbanization and industrialization process. This ...

Abstract: AbstractSulfoaluminate cement–based grouting materials (SAGMs) are frequently employed in projects concerning reinforcement and repair. Retarders are often added to SAGMs to improve their workability by delaying the hydration ...
