| Abstract: | This paper introduces a deep foundation pit support project in urban area ofJinan, which was constructed under the conditions of complex surrounding environment and limited land area. The composite soil-nailing wall support technology used in this project is analyzed, with its characteristics of various forms and flexible combination, the advantages of each component in the assembly gave full play. The construction points and key technical measures of each construction procedure are summarized. The monitoring data show that the small displacement and deformation have no adverse affects to the surrounding environment and the support system has good effect. |
