采用分层总和法计算模型对东改沿线非桩基段输水结构的沉降 (全面 )进行了计算 ,并取适于广东地区的经验变形模量进行计算 ;对碎石桩处理的软弱地基 ,通过理论分析和现场试验综合确定的复合地基变形模量。建议局部地段加强检测或设计改进处理方案 ,以减少沉降 ,并提出了为控制沉降所要求的地基的变形模量值 ,作为地基检测的控制标准。
The stratified sum method was used to calculate the settlement of the water conveyance structure of the non-pile foundation along the East Dongzai line, and the empirical deformation modulus suitable for Guangdong area was calculated. For the weak foundation treated by the stone column, Deformation Modulus of Composite Foundation Synthesized by Theoretical Analysis and Field Test. It is suggested that the detection and design improvement measures should be strengthened in some areas to reduce the settlement. The deformation modulus of the foundation required for settlement control is proposed as the control standard for foundation inspection.
