重载作用下软土地基加固技术在上海罗泾港区矿石堆场的研究与应用

Research on and application of soft ground consolidation technique under heavy load on Shanghai Luojing harbor area stacking yard

根据上海港罗泾港区二期矿石码头工程的工程特点和地质情况,针对重载作用下浅层无黏性土和深层淤泥质软土地基的加固处理,提出了"浅层处理、分级加载、使用期调整"的地基加固创新思路。并给出了相应的施工参数,通过工程实际应用,取得了成功。

According to the engineering characteristics and geologic condition of Shanghai Port Luojing Harbor Area Phase Ⅱ Ore Terminal project, the innovative idea of ＂shallow layer treatment, stepped loading ＆ adjustment during operation＂ is put forward for soft ground treatment with shallow-layer noncohesive soil and deep-layer muddy soil, with relevant construction parameters provided. It has been proved successful by the real engineering practice.
