Experimental Study And Numerical Analysis Of The Column Plate Anchor Cable Retaining Walls

In thesis, The column-slab anchored retaining wall along Shaohuai highway is analyzed by using the method of field test and numerical simulation:1.In allusion to retaining structure mentioned above,The position of the field test equipments and testing method as well as some relevant laboratory experiments are designed and introduced in detail,which could be a good reference for such laboratory experiment and field test of similar project.2.In order to obtain the earth pressure behind the wall, earth pressure cells are installed behind the retaining structure,and also the strain gauges are installed along the cable to obtain the the axial load distribution of the cable,the anchorage rope dynamometer are installed at the head anchor to obtain the change of prestressing in long term,and also the steel-string transducer are installed in the anchord to obtain axial load distribution of the anchor.3.A two-dimensional numerical model of finite difference for column-slab retaining wall was established, the earth pressure, displacement of the column-slab retaining wall,the banding moment of column and the axial load at the anchoring section of cables were caculated.4.Comparing the result of finite difference to the field test, it is indicated that good agreement is found between the result of calculation and the field test.5. The applicability of column retaining wall was analyzed and also it's table a proposal to the design approach.
