软弱结构面 meaning in English
weak structural plane
Examples
- The classification of the surrounding rock divides the rock in the respect of quantitative classification and gets the qualitative gradation of the engineering rocks by correction of underground water , correction of weak structural plane and correction of original stress field
围岩分级主要从定量分级的角度对围岩等级进行划分，并通过地下水修正，软弱结构面修正和初始应力场修正，得到修正后的工程岩体质量等级。 - The landslide feature of the expansive soil is analyzed . the stability of the expansive soil slope is largely dependent on the weal link . the slope stability analysis of the expansive soil should consider the weathering , so all the analysis should be classified to two different types : weathered layer and non - weathered layer
对膨胀土路堑边坡滑坡特点进行了分析，指出膨胀土边坡主要受软弱结构面控制，提出了膨胀土边坡稳定分析应分为风化层和深层未风化层的方法，并建议了不同部位土的抗剪强度指标取值方法。 - Stability of rock slopes is generally controlled by the structure of rock masses , especially the soft structure surfaces . analysis of rock mass structures is a key to establish geological models and numerical simulation and a foundation to assess the stability of rock slopes . the weak structure surfaces are mainly bedding planes , faults , joints , schistosity plane and contact zones of intrusive bodies . since they are different in genesis and scale , the rock masses are different in features and mechanical intensities . based on the combination of rock structure bodies , 15 basic modes of deformation and failure of rock slope are systematically summarized . the deformation and failure of rock masses actually result from the recombination and rearrangement of these rock bodies . there are 11 types of rock mass structures and various deformation and failure of bank slopes are present in the reservoir area of the three gorge project
岩体结构，特别是软弱结构面对基岩斜坡变形与破坏具有显著的控制作用，岩体结构模式分析是建立斜坡地质模型和数学模型的关键和评价斜坡稳定性的基础。岩层层面断裂构造节理裂隙片理与劈理以及侵入体和围岩的接触带等是控制基岩斜坡稳定的软弱结构面，这些成因不同大小不一的结构面将岩体分割成性质各异力学强度不均的各种岩体结构体，构成了15种基岩斜坡变形破坏的岩体结构基本模式。不同结构体的重新组合与排列是斜坡失稳的内在原因。 - Thirdly , the paper point out that the key reasons of swelling soil subgrade ' s collapse are swelling soil ' s expand - shrink property , cranny property , strength decrease property and weak frame surface property . as the result of this , the paper provides theoretical foundation for evaluating the stability of swelling soil subgrade ' s side slope
指出膨胀土的胀缩性、裂隙性、强度衰减性、软弱结构面是导致膨胀土路基边坡滑塌的根本原因，从而为准确评价膨胀土路基边坡的稳定性提供理论依据。
