Research Of Composite Foundation Settlement With Cement-Soil Mixed Pile In Xinglin Expressway

Recent year, along with the economic development unceasing development, our country infrastructure construction scale is increasingly big, the more and more many civil engineering needs to carry on processing to the natural foundation. In the engineering construction can meet the weak subgrade frequently, the weak subgrade processing method emerges one after another incessantly, the water soil stirs the pile compound ground then is one of ground processing methods, because has the construction cost lowly, the construction speed quick and so on the merits, in each kind of project widespread application, has the widespread prospect. But its corresponding fundamental research work compares the lag actually, has restricted this method development and the consummation. This article in summarizes predecessor's fundamental research and in the experimental achievement foundation, stirs the pile subsidence formula to the existing water soil to carry on the discussion, the analysis formula rationality and the conditionality, and using the ANSYS finite element software, the union project example, stirs the characteristic to the engineering structure sewer soil which the pile compound ground group pile subsidence distorts to carry on the value simulation, discovers the cement earth to stir the pile compound ground the bias field, the distortion characteristic and so on some basic rules.
