摘要
结合青岛港前湾港填海软基加固工程,对管井降水联合"轻夯多遍"地基处理新工艺加固填海软基进行现场试验研究。以青岛港前湾港四期工程1#～4#泊位的3个试验区为例,采用3种不同的试验参数进行施工,通过对试验前后各项检测数据进行整理和对比分析,证明了此新工艺对加固填海软基是有效可行的,同时对试验中3个试验区的加固效果进行比较,得出了相对优化的施工参数,进一步完善了该套工艺的技术参数。
Using the Bay of Qingdao Port 1# ～ 4# berths sea reclamation soft foundation consolidation as an example,a site test about tube well dewatering associate with ‘low-power re-ram ’ to deal with reclamation of soft foundation was introduced.Different experimental parameters are adopted in three experimental zones proposed.By comparing and analyzing tryout test data before and after the treatment,the technology that deals with reclamation of soft foundation is confirmed tobe feasible and effective.At the same time,optimizations of construction parameters have been proposed through comparing the effect of reinforcement,which can serve as a reference for similar engineerings.
