【摘要】：基于飽和-非飽和滲流理論,運(yùn)用Geo-studio軟件中的Seep/w模塊研究了裂隙各向異性與不同降雨強(qiáng)度共同作用下邊坡的入滲規(guī)律。結(jié)果表明,當(dāng)降雨強(qiáng)度小于裂隙滲透系數(shù)時(shí),雨水入滲受降雨強(qiáng)度控制;當(dāng)降雨強(qiáng)度大于裂隙滲透系數(shù)時(shí),雨水入滲受裂隙滲透系數(shù)控制;在相同的降雨時(shí)間與降雨強(qiáng)度條件下,裂隙越短則裂隙內(nèi)的體積含水率越高,裂隙角度越小對(duì)邊坡內(nèi)部體積含水率影響越大;增大降雨強(qiáng)度或增加降雨時(shí)間,均會(huì)削弱裂隙各向異性對(duì)邊坡滲流的影響。
[Abstract]:Based on saturated-unsaturated seepage theory, the infiltration law of slope under the joint action of fracture anisotropy and different rainfall intensity is studied by using the Seep/w module of Geo-studio software. The results show that Rain Water infiltration is controlled by rainfall intensity when rainfall intensity is less than fracture permeability coefficient, and Rain Water infiltration is controlled by fracture permeability coefficient when rainfall intensity is greater than fracture permeability coefficient. Under the condition of the same rainfall time and rainfall intensity, the shorter the crack is, the higher the volume water content in the fracture is, and the smaller the fracture angle is, the greater the influence on the internal volume water content of the slope is. Increasing rainfall intensity or increasing rainfall time will weaken the influence of fracture anisotropy on slope seepage.
