Settlement Analysis of the Soft Soil Improvement by Preloading and Prefabricated Vertical Drains

The deep foundation pit in soft soil was supported by concrete angle stays,in whichthe deformation uncontrolling of foundation pit for traditional support was overcome.Fromthe engineering,it had such advantages as the definite knowledge of loaded regi me and the reliable structure,in which not only the foundation pit's deformation was controlled,but alsoits convenient construction,meanwhile the security of surrounding environment was guaranteed.
