Abstract:Anchor cable with scattered compression force is a new type of anchorage measure ancl has a wicle range of application to the slope protection, landslide remedial works ancl foundation ditch support. This paper studies in situ pull-out test of the new anchor cable and introduces the test procedure and method to test the tension of the new anchor cables based on a practical landslide remedial project. Furthermore, some problems about anchor cable test are discussed in this paper as well. The results obtained from the study provide some effective clata for the design ancl construction, which have important applicative values.

Abstract:Based on an actual construction project,a tunnel construction procedure with pipe shed support is simulated with three-dimension nonlinear FEM.The conclusion is: the pipe shed support have very tangible influence on controlling ground settlement,horizontal displacement of the side wall and plastic deformation.The influence of pipe diameters and spaces is limited on the displacement maximum,but has greater effect on the pipe internal stress.The influence of excavation lengths and the thickness of grout strengthening on tunnel structure are more obvious.The actual monitoring results demonstrated that the numerical simulation results are reliable and can be used as design and construction reference for pipe shed support engineering.

Abstract:丹东盘道岭隧道始建于1981年，隧道限界高度仅为3．5m，且隧道内漏水严重，已不能满足行车需要。隧道维修设计中为了不破坏原隧道衬砌，采取了隧道下卧方案。施工中为了控制原衬砌结构下沉量，采取了跳槽马口开挖方式。经实践证明采取的措施是有效的。
