摘要
分析了预灌浆在破碎和含水地层中具有的充填、压密、粘合及固化等改良岩体原有物理力学性能的综合作用。预灌浆的灌浆范围、灌浆压力p、浆液扩散半径R以及浆液配比等设计参数的确定具有关联性。对浆液材料的选择及应用进行了探讨。
The comprehensive effects of filling in, compacting, agglutinating, solidifying and reclamation of rock of pre-grouting in broken aquifer are analyzed. The design parameters such as scope and the pressure p of grouting, the radius of diffuse, and the ratio of W/C have relevancies. The paper also discusses the selection and application of the grouting mortar.
