| Abstract: | Based on the actual cases study of many cities in China, authors analysed the deformation characteristics and control indexes of retaining structure and surrounding ground of the foundation pit engineering of urban rail transit. Measured results were processed by statistical analysis. According to related research results and technical codes, the recommended controlled values for deformation were given for different soils which can reasonably evaluate the safety state of foundation pit engineering. Deformation monitoring controlled indexes are affected by many factors;, in-depth research should be carried out to improve the safety risk control level of foundation pit engineering. |
