软土地区大型船坞底板优化设计

采用PLAIXS软件分析了船坞开挖卸荷和坞墙侧限对底板承载力的影响,结果表明,目前底板设计没有考虑土体开挖的卸荷效应和坞墙的侧限效应显得过于保守。考虑桩土共同作用,用理论的方法分析了船坞底板的受力特性,得到了不同土层分布对底板沉降和土体荷载分担的影响。计算结果与有限元计算值进行对比分析,验证了该方法的正确性。

Optimum design of slab for large-scale dock in soft soil

This paper analyzes the influence of excavation and dock wall on the bearing capacity of the dock slab by software PLAXIS.The results indicate that the current design method is conservative.The pile-soil interaction is taken into account to obtain the vertical load-settlement relationship of the dock slab and the load shared by the pile and soil.The theoretical model agrees with the fact quite well.The comparison of results of the finite element has been carried out with calculated results,which proves its ...
