引言本项研究的意图在于通过将大部分外荷分布至浅层表土以减轻作用于基底的压力,而浅层表土则可以比较容易地用地基加固或预压的方法予以改善。由图1可见,外荷P将通过楔形基础以水平荷载P_n传递给周围土体,并以竖向荷载P_v传递给基底土体。作用于楔形基础外侧竖向表面的摩阻力将
INTRODUCTION The purpose of this study is to reduce the pressure acting on the substrate by distributing most of the outburst to the shallow topsoil, while the shallow topsoil can be easily improved by foundation strengthening or pre-pressing. It can be seen from Fig. 1 that the external load P will be transmitted to the surrounding soil by the horizontal load P_n through the wedge-shaped base and transmitted to the base soil by the vertical load P_v. The frictional resistance acting on the vertical surface outside the wedge foundation will
