摘要
以沪通铁路Ⅵ标段工程为依托,通过ANSYS数值模拟软土路基路堤分层填筑,分析在分层填筑过程中的沉降规律,并在软土路基路堤分层填筑过程中,严格监测路基的沉降和变形。研究结果表明:软土路基路堤在分层填筑过程中,路堤中线地表处的沉降量最大,然后向两侧逐渐减小,横向影响范围主要为路基底面宽度;分层填筑过程中,路堤中心最大沉降量为9.20 mm/d,边桩最大水平位移为0.53 mm/d,均满足设计要求。
Analyze the sedimentation rules of embankment during the placement in layers via ANSYS numerical simulation of soft soil subgrade and embankment placement in layers based on VI section of Shanghai--Nantong railway project. And it strictly monitored the subgrade sedimentation and deformation during the placement in layers of soft soil s e and embankment. The results show that the earth surface of embankment midline has the maximum sedimentation during placement in layers which is gradually decreased towards both sides. The horizontal influence range is mainly the subgrade base. The maximum sedimentation at the center of embankment is 9.20 mm/d and the maximum horizontal displacement of side pile is 0. 53 mm/d, meeting the design requirement.
