江津成品油输油管道某站场地基强夯处理研究

Study on soft soil foundation treatment by the dynamic compaction of product oil pipeline yard in Jiangjin

结合重庆市江津区成品油输油管道站场拟建区的地质条件,采用强夯法对该场地的软土层进行了地基加固处理,通过监测,分析了强夯点的沉降量和空虚水压力变化规律,并对比了不同强夯方案下的孔隙水压力和沉降变化规律,经固结试验表明,相同的强夯能量作用下,采用锤重12 t和落距10 m的方案压实效果更好。

Combining with the proposed product oil pipeline station geology conditions in Jiangjin region of Chongqing city,the paper carries out soft stratum consolidation treatment by applying dynamic compaction method,analyzes the settlement volume of the dynamic compaction point and void water pressure changing law through monitoring,and compares pore water pressure and settlement changing law under different dynamic compaction schemes.The consolidating experiment shows that：under the action of similar dynamic compaction energy,the dynamic compaction effect will be better by applying the scheme of 12 t of hammer and 10 m of settling distance.
