screw plate test

Mechanism of screw plate load test was explained with the solutions,and allowable beating capacity and deformation modulus of lay- ered subsoil were determined.

基于多层地基内部作用竖向集中力的广义Mindlin解和竖向均布圆形荷载的沉降计算公式,从理论上探讨了螺旋板载荷试验的受力机理,据此建立了螺旋板载荷试验确定地基容许承载力与变形模量的理论公式。

The deformation modulus of foundation soil is determined via the screw plate load test,so as to establish the relationship between deformation modulus and compression modulus.

通过螺旋板载荷试验确定地基土的变形模量,并使之与压缩模量建立一定的关系;通过进行深度对地基土压缩模量、变形模量的影响分析,得出:压缩模量和变形模量随深度加深而增大;通过进行载荷板面积对变形模量的影响分析,得出:变形模量随着载荷板宽度和载荷大小而变化。
