新疆昌吉中风化泥岩地区锚杆基础承载试验研究
Experimental Research on Bearing Capacity of Anchoring Foundation in Intermediary Weathered Mudrock Areas in Changji, Xinjiang
摘要
Abstract
In order to obtain the design parameters of rock anchors in mudrock areas in Changji,Xinjiang,typical intermediary weathered mudrock areas are chosen to conduct on-site tests of anchoring foundation.Through these tests,the uplift resistance limitation and grouped anchors' effect factor of anchoring foundation are obtained,and the change rules of axial force,displacement and stress of anchor are analyzed.The proper values of foundation anchoring depth and impacting range are proposed.The results of on-site tests are also verified by numerical analyses.The results show that,in intermediary weathered mudrock area in Changji,the uplift resistance limitation of single anchor foundation is 450 kN,the grouped anchors' effect factor is 0.8,the proper anchoring depth is 3 m,and the proposed protection range of foundation test is 3 m.The test results will provide references for the design of anchoring foundation of transmission line in Changji mudrock area.关键词
