Tests and analyses of shearing wave velocity in the Xi’an earth fissure deforming belt

摘要: 文章依托西安地铁二号线工程,对跨地裂缝的地层进行剪切波速测试,通过对测试结果的分析确定了地裂缝变形带内的剪切波速变化规律,给出了地裂缝变形带地裂缝上盘影响带宽度小于3.5～5.7m,下盘影响带宽度小于2.0～3.3m,其结果与现行的相关规程中的参数吻合,为规程提供了强有力的科学依据。Abstract: Supported by the Xi’an Metro Line-2 Project,the shear wave velocity tests were carried out initially in the earth fissure deforming belt.The test results show that the distribution of shear wave velocities is related to the distance from the center of the earth fissure,that is,the nearer the distance to the center,the lower the velocity in the strata.The width of the deforming belt can be determined with the distribution of the velocities.The results of the test coincide with the standard of the...
