软弱结构面对边坡岩体变形及边坡的失稳破坏起控制作用,其准确识别和预测边坡变形破坏以及设计治理等具有重要意义. 以井壁地层中声波的传播特性为基础,分析了斯通利波的衰减与地层的固有衰减,以及与井壁地层的渗透性之间的关系,同时,对反射斯通利波的强弱与地层裂缝的宽度和充填性之间的关系进行了探讨. 通过滑坡勘查应用实例,论述了声波的属性参数和特征,在划分岩层、识别裂隙和孔洞以及评估岩体力学性质中的实用性和准确性

Rock deformation and unstable failure of slope is controlled by weak structural plane whose identification and evaluation is greatly influenced by deformation failure prediction of slope and design treatment.Based on the propagation characteristics of acoustic wave in shaft lining strata,attenuation of stoneley wave and inherent attenuation of strata are analyzed and permeability relationship among shaft lining strata is researched.The relationship between reflected stoneley-wave intensity and the width and filling ability of strata crack is studied.By application example of landslide investig...
