摘要
介绍了超深水泥土搅拌桩在软土加固工程中的应用,通过进行室内渗透试验和抗压试验,测定不同土层处桩体的渗透系数及加固体强度,并对试验结果进行分析。试验表明:超深水泥土搅拌桩能够显著降低砂性土层的渗透系数,增强土体的强度。采用超深水泥土搅拌桩加固软土地基是可行的。
In this article, a construction practice of reinforcing soft soil by applying supper-deep cement-soil mixing pile is introduced. Through coring in-situ and laboratory experiment, horizontal and vertical permeability coefficients and strength of test piece from the pile body in different depth are got. The results of laboratory experiment shows that, cement-soil deep mixing method can significantly improve the anti-permeability of sand soil and strength of the soft soil, and it proves that the supper-deep cement-soil mixing pile will be competent for water exclusion and strengthen the sort soil. It＇ s feasible to reinforce the soft soil by applying supper-deep cement-soil mixing pile.
