| 摘 要： | 大型工程建筑对基础沉降量控制的要求非常高,进行桩端注浆是减小群桩基础沉降量的有效方法,并在国内外得到了广泛应用。文中结合现场试验,提出了利用注浆后单桩静载试验结果反求土的参数,而后运用剪切变形传递法计算注浆后群桩基础的沉降量这一方法,结合现行规范进行了验证。

| Abstract: | Large-scale engineering construction has higher requirement for base settlement control.Pile tip grouting is an effective measure to reduce pile group base settlement,and has been widely applied at home and abroad.Combined with site test,this paper puts forward the method to seek for soil parameters in reverse with the result of single pile static load test after grouting and then calculate pile group base settlement after grouting with shearing deformation transfer method,and verifies it combined with the ... |
