摘要
结合南沿江城际铁路望虞河特大桥DK224+658里程处跨204国道连续梁2个主墩的深基坑施工设计实践,对深基坑钢板桩方案及工况进行设计探究,通过方案及工况设计后,对其进行相关验算,并对施工过程中位移监测进行布置设计。通过对该实践工程的深基坑设计探究,拟制出一套技术可行、安全可靠、经济合理及现场可实施的方案。
Based on the deep foundation pit construction design practice ofthe two main piers of the continuous beam of 204 National Highway at DK224+658 of Wangyuhe Bridge of Nanyanjiang Intercity railway,the steel sheet pile scheme and working conditions of deep foundation pit were designed and explored.After the scheme and working conditions were designed,the relevant checking calculation was carried out,and the displacement monitoring layout was designed in the construction process.Based on the deep foundation pit design of this practical project,a set of technically feasible,safe and reliable,economically reasonable and practicable scheme is drawn up.
