Analysis on Force Monitoring in Underwater Curved Pipe Jacking Construction Process
Based on a sponge city construction project in Zhenjiang,Jiangsu Province,this paper conducts the whole process monitoring of steel bar internal force and earth pressure in pipe jacking construction,and studies the monitoring data.The results show that the bending of the pipe jacking axis causes the change of the internal force of the longitudinal steel bar to be larger than that of the circumferential steel bar;the existence of the mud sleeve effectively reduces the earth pressure,and its integrity will affect the uniformity of the earth pressure distribution.
