挂板斜插式桩板墙土压力分布模式试验研究

斜插式桩板墙是支挡结构与景观绿化相结合而形成的一种新型道路边坡支挡形式，目前已在实际工程中得到应用。由于该结构允许墙背土体主动变形，墙背不完全垂直、光滑及墙背地下水可自由渗透等方面与传统直挡板桩板墙相比具有特殊性，在一定程度上影响了挡墙墙背土压力的发挥。为此，通过室内模型试验，对比分析了斜插式桩板墙与传统直挡板桩板墙在土压力分布模式上的区别。

Experimental Study on Distribution Mode of Soil Pressure of Oblique-inserting Slab-pile Wall of Hanging Slab

The oblique-inserting slab-pile wall is a new type of road side slope retaining form combined retaining structure with landscape greening, which has been applied to the practical engineering. Due to such special characteristics of the structure compared with traditional sheet pile wall as allowing the active deformation of wall back soil, incomplete vertical and smooth wall back and the groundwater behind the retaining structure free penetration, which, to a certain extent, affects the wall back soil pressure of retaining wall. This paper, through the indoor model test, is to analyze the difference between oblique-inserting slab-pile wall and traditional sheet pile wall on earth pressure distribution.
