Determination of rock resistant coefficient based on Mohr-Coulomb criterion for underwater tunnel

Abstract：According to the load-structure method,the wall rock with lining call bear the load caused by the surrounding rock,and the rock resistant coefficient(RRC)is a key parameter for evaluating the capacity of this wall rock.Based on theMohr-Coulomb yield criterion,this paper develops a formula for calculating the RRC,which has been applied to the real engineering project,such as Xiamen Xiangan East Passage Underwater Tunnel Project.The fact shows that this formula is helpful for designers to determine the RRC value. 作者： Author： Zhong-ren TU[1]  Qiang YANG[2]  Qi-ming SHEN[3]  Xiao-wen WANG[3] 作者單位： State Key Laboratory of Hydroscience and Engineering,Tsinghua University,Beijing 100084,China;School of River and Ocean Engineering,Chongqing Jiaotong University,Chongqing 400074,ChinaState Key Laboratory of Hydroscience and Engineering,Tsinghua University,Beijing 100084,ChinaSchool of River and Ocean Engineering,Chongqing Jiaotong University,Chongqing 400074,China 期 刊： 浙大學(xué)報(bào)（英文版）（A輯：應(yīng)用物理和工程）   ISTICEISCI Journal： JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE A 年，卷(期)： 2008, 9(9) 分類號(hào)： U45 TU9 Keywords： Rock resistant coefficient(RRC)    Mohr-Coulomb yield criterion    Rock mechanics    Underwater tunnel    機(jī)標(biāo)分類號(hào)： U4 TD3 機(jī)標(biāo)關(guān)鍵詞： surrounding rock    yield criterion 基金項(xiàng)目：
