crust stress meaning in Chinese
地壳应力
Examples
- One of the key elements is to analyze and know initial crust stress field to solve the problem . while traditional theory , such as classical pressure theory and theory of dispersed medium pressure , can not meet the requirements of engineering
合理解决该问题的关键因素之一就是分析研究和深入认识初始地应力场。古典压力理论、散体理论等传统理论已经不能满足工程建设的需要。 - Displacement function means for calculating geostress in fem analysis of underground houses is used , based on crustal stress data of underground cavern of pump water station of tong guanshan yixing to store energy , applying the displacement function theory and 3d nonlinear fem , the thesis simulates a displacement field applied the boundary in engineering area and obtain the initial crust stress field through load function in ansys . the result shows that the error between regressed ones and actual ones is controlled in allowed limit and supply the important data for building and design
根据宜兴铜官山抽水蓄能电站地下厂房区的地应力实测资料，运用位移函数法理论，采用三维非线性有限元计算方法，反演出施加在厂房区边界上的位移场，借助州sys有限元分析软件，获取模型边界节点的坐标信息，然后通过ansys软件的载荷函数将边界位移程序化施加到模型边界上，最后得到整个区域的初始地应力场，结果表明回归后的地应力值与实测值接近，为地下工程的施工设计提供了重要的资料。 - The following are such theories and methods as nonlinear theory considering interaction between support and rock mass , which , based on quantity analysis technology and actual data of initial crust stress , can simulate complex geological condition , carven shape and supporting so that provide important reference for analysis of stability of rock mass around underground carven and design of supporting
随之而来的是考虑支护与围岩共同作用的非线性理论和方法。这些理论和方法一般都以数值分析为手段，以实测地应力资料为基础，能模拟复杂的地质条件、洞室形状及支护措施，从而为地下洞室围岩稳定性评价和支护设计提供重要的参考依据。 - When there is original stage support only , the load ratio of surrounding rock gets more and more bigger with the increasing of crust stress , correspondingly , the load ratio of initial stage support gets smaller . when the initial stage support and the second support act each other , the load ratio of surrounding rock is more than fifty percent , and it has little change with the increasing of crust stress . the whole analysis of the surrounding rock and support shows that the bottom arch of liner and the feet of liner have serious stress concentration , so do the sidewalls and the foot of a wall of the surrounding rock
通过屈曲理论分析结果对比表明，弹性屈曲和突变失稳分析的结果比非线性屈曲分析的结果要大得多，非线性分析由于考虑了材料非线性和几何非线性，因而结果与实际接近实际；当只有初期支护时，随着地应力的增加，围岩的荷载分担率增大，相应地，初期支护的荷载分担率就减小了；当有初期支护和二次衬砌共同作用时，围岩的荷载分担率在50以上，这一分担率随地应力的增加其变化不大；支护和岩体的整体分析表明，衬砌底拱及拱脚处应力集中严重，隧道岩体侧墙及墙角围岩的应力集中也较大。 - At last , the analysis of the redistribution of the initial crust stress and the distribution of the plastic area is made ; the stability evaluation of the rock mass around the cavern is provided . the outcome is conformed with the reality . then applys the approximately equivalent dissolved rule , and considers the action of anchor staff to consolidate the rock mass , and correspond model is established , nonlinear finite element m ethod is applied to analyze the effect of the supports , the result shows that the action of anchor staff is obvious and deformation and stress state of the rock mass is greatly approved . so , the result conforms that the idea and the means used in the thesis is applicable
最后运用非线性有限元对厂房开挖后围岩的应力重分布和塑性开展区的分布作了分析，评价了厂房的围岩稳定性，其结果与实际开挖情况基本吻合，针对围岩稳定性评价的结果，提出了锚固方案，运用等效概化原理考虑锚杆的作用，建立了采用系统锚杆加固后的地下厂房围岩的三维弹塑性模型，运用非线性有限元分析了加固效果，结果表明锚固作用明显，围岩变形明显减小，围岩内的应力状态大为改善，从而验证了本文所采用的研究思想和方法是切实可行性的。
