摘要
文章依托江苏镇江某海绵城市建设工程,开展顶管施工管节钢筋内力、土压力全过程监测,并对监测数据进行研究.结果表明:顶管轴线的弯曲造成纵向钢筋内力变化幅度相较环向钢筋更大;泥浆套的存在有效削减了土压力,其完整性会影响土压力分布的均匀性.
Abstract
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.
