| 摘 要： | 由于深层搅拌桩复合地基压缩模量与桩端土压缩模量、桩尺寸、荷载等参数相关性差,所以准确计算复合地基压缩模量的难度较大。根据格栅与土共同作用的原理,推导出模量的计算式。通过高层建筑结构地基静载荷试验的资料对比,证实了压缩模量的计算式是适宜的。

| Abstract: | The formula for deep-mixing pile composite foundation on the code is bad with correlation of the geologic strata parameter(such as soil modulus on the end of pile foundation,pile foundation size,subsidiary stress etc).So,it is more difficult to accurately calculate modulus of grid composite foundation.Based on the interaction of grid and soil,a formula about compressive modulus of grid composite foundation is deduced.By comparing the field static load test results of engineering of high-rise building,it is proved that the formula is reasonable for calculating for grid foundation for high-rise buildings. |
