【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。更多还原

【Abstract】 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.更多还原
