surrounding rock classification meaning in English
围岩分类
Examples
- The idealized mode distinguishing method in surrounding rock classification
围岩分类中的理想模式识别方法 - Fuzzy judgment advanced model and its application for surrounding rocks classification in tunnels
隧道围岩分类模糊评判改进模型及应用 - ( 3 ) a set of classified scheme is established , and surrounding rock classification fast estimate system based on fuzzy inference is developed , which open a new way for estimating classification of surrounding rock
( 3 )制定了一套适用于鹧鸪山隧道施工阶段的围岩分类方案，并研制了基于模糊逻辑推理的围岩类别快速判定系统，为围岩类别判定开辟了一条新的途径。 - Furthermore tunnel structure commonly is designed by analogy method . on design , often , normally in view of safe consideration , adopt the method that reduction surrounds rock classification and uses fussy construction technology . so as soon as coming , engineering investment is certainly increased and construction project time is prolonged
且隧道结构一般按类比法设计，出于安全考虑，设计上一般采用降低围岩类别，使用复杂的施工工艺来提高施工的安全性，这样无形中增加了工程投资费用且延长了施工工期。 - ( 2 ) taking the geology analysis as main way and combining the pre - test , predicating the tunnel ' s main geology condition ( rock quality , surrounding rock classification , long - wide joint , fault , ground water , crustal stress ) , and predicating the main potential disaster ( collapse , breaking water , rockburst , large deformation ) ( 3 ) employing the stress test result and inverse analysis of the stress field , finding out the crustal stress " s distributing rule along the tunnel axes section : the highest crustal stress is 24mpa near the deepest spot , and predicting that the k2 + 260 ~ k3 + 000 likely to be the high crustal stress segment for this tunnel
通过地质分析、类比分析、监控量测、数值模拟、神经网络等方法，对鹧鸪山隧道潜在的主要地质灾害(塌方、涌水、岩爆和大变形)进行了预测预报( 3 )在现场地应力测试成果的基础上，运用数值计算进行应力场反演，基本查明了沿隧道轴线剖面的地应力分布规律：地应力量级在最大埋深附近达到最大值24mpa ，并预测k2 + 260 k3 + 000段将很可能成为鹧鸪山隧道的高地应力段。 ( 4 )塌方往往与断层破碎带及千枚岩相联系。
