板桩式海堤结构有限元数值模拟分析

为改变浙江沿海海堤功能单一，土石料用量大的缺点，开展新型海堤结构研究。对板桩式海堤结构进行有限元数值模拟研究，分析在竖向荷载及回填土压力作用下，结构的变形及承载能力。可以得出，桩土的位移量均不大，土体未发生明显的塑性变形，桩身应力不大，可进行实际工程的应用。

Numerical Simulation Analysis of Finite Element of Sheet Pile-type Seawall Structure

The paper studies new type seawall structures in order to make better use of coastal seawalls and reduce consumption of earth rocks. Finite element numerical simulation was conducted on sheet pile-type seawalls, analyzing the struetural deformation and bearing capacity under the effect of vertical load and haekfil pressure. The structure can be put into practical use as results show that the displacement is small, plastic deformation of soil is unobvious, pile stress is small.
