L型填芯挡土墙受力与变形的数值模拟研究

为了研究L型填芯挡土墙的受力特性，采用FLAC3D有限差分软件进行了数值仿真分析，根据数值分析的结果对L型填芯挡土墙与L型挡土墙对挡墙的水平应力、挡墙侧移进行研究，进而在力学性能与工程应用方面进行了对比分析。分析结果表明：L型填芯挡土墙可以有效控制其自身水平位移；箱式底板和立板连接处应注意应力集中，加强连接。

Numerical Analysis of Stress and Deformation Characteristics of L-Shaped and Soil Filled Retaining Walls

The stress and deformation characteristics of a model LShaped, soil filled model retaining wall as well as a conventional LShaped retaining wall was numerically studied by using a commercial finite difference software FLAC3D. The lateral earth pressures acting on both wall types and the lateral deflection of both walls are investigated in this paper. The results indicate that, LShaped and soil filled wall can effectively control the lateral deflections. It is also concluded from the numerical analysis that the stress concentration is occurred at the connection point between the bottom slab and vertical box.

It is also concluded from the numerical analysis that the stress concentration is occurred at the connection point between the bottom slab and vertical box.
