And the consumption which are caused by the deformation of the rock mass and the consumption which fill all the void space of the joint can be got . then the block coefficient k of the this geologic condition can be got by the actual consumption of the injection grout in the practical grouting 本论文中主要通过有限元法来计算岩体的变形,并进而求得由岩体变形引起的那部分注浆量和完全充填节理裂隙的注浆量,再根据实际工程的实际注浆量来计算试验所代表的地层的充填系数k 。
