摘要
提出了一个在土骨架不可压缩假定下分析桩底灌浆压力场的方法。该方法在径向渗流理论基础上考虑了浆液与水之间的相互作用,求解了灌浆引起的超静水压力及其梯度、灌浆量与浆球半径关系、灌浆量的计算,并给出了由现场灌浆资料确定浆液渗透系数的方法。讨论了一些对灌浆压力场有重要影响的参数。
Proposes a method of analyzing grouting pressure field at pile bottom based on the proposition of uncompressed soil skeleton, the interaction of grout liquid and water is considered in this method. The excessive hydrostatic water pressure, the water pressure gradient, and the relation between volume and radius of grout globe are presented. The calculation of grouting volume, and the determination of permeability of grout liquid from grouting data using the radial seepage theory are introduced. The parameters having effects on the grouting pressure fields at pile bottom are discussed.
