%X 采用现场试验，从土体变形规律及钢花管的受力特性两方面研究多次注浆钢花管桩在堆载预压软基处理中的应用。试验结果表明多次注浆钢花管桩能有效控制整个堆载预压过程中土体侧向位移，多排桩均发挥了作用，且前排桩发挥作用更大，注浆钢花管桩有效防止了堆载预压过程中地基土体滑移破坏的可能。对于类似场区处理具有很强的指导意义。<br />
Based on field tests, the application of grouting steel pipe piles in soft foundation treatment under pile preloading is studied repeatedly from two aspects: soil deformation law and stress characteristics of steel pile. The test results show that multiple grouting steel pipe piles can effectively control the lateral displacement of the soil during the pile preloading. Multiple rows of piles have played a role, especially the front piles. The grouting steel pipe piles can effectively prevent the possibility of slippage damage to the foundation soil during preloading, which has significant guidance to the treatment of similar fields.
