Analysis of Soil Disturbance Caused by Pipe Jacking Construction

Abstract:

Open caisson is one of the common used structures, as a working shaft in pipe jacking project. Disturbance of the soil behind the reaction wall of open caisson (SBRWOC) will reduce the efficiency of jacking, and affect safety of site operation and control. However, there are few studies on disturbance of SBRWOC. In this paper, combining the project of parallel pipe jacking passing under the Guan River in Jiangsu Province, China, field monitoring of SBRWOC is carried out during pipe jacking construction, including earth pressure and lateral displacement of SBRWOC. The maximum lateral displacement of SBRWOC is about 27 mm and the maximum earth pressure is 98.5 kPa. These results are useful for engineers to study disturbance characteristics of SBRWOC and reduce environmental impacts during pipe jacking construction.
