7、The obtained results are shown that the anchor bolts supports in the fissured rock mass is good to raise the safety of the whole structure of grottoes.
2、Firstly, the basic rule of seepage in fissured rock mass and the mechanism of the effect are studied.
6、The results show that the probability distribution characteristic of the vertical permeability coefficient in fissured rock zone is much close to the log-normal distribution.
3、In this paper, the basic characteristics of the seepage of contact fissured rock mass under the stress action are studied.
9、The magnitude of unloading velocity and initial stress mainly influence strength and amount of sub-cracks on fissured rocks, but little on the law of expanding mode and deformation.
8、In order to study the rule of seepage flow in fissured rocks, the influence of permeability of fissures in different intersection angles and direction is compared.
1、The concentrated leakage passage in fissured rock is studied with dummy heat source method.
5、In combination with fissured rock strike, dip Angle and distribution seepage flow in fissured rocks is determined by use of single well tracer method for the area under study.
4、The fissured rock seepage flow field of Xinanjiang river right dam is studied by using the isotope tracer method.
