强夯法加固碎石填土地基的夯后效果检验是比较困难的。 攀枝花市某工业厂房用单击为3200KN·m的夯击能、强夯加固平均厚度达15m的碎石填土地基的效果检验,是以120kg重型动力触探和静载荷试验(浅层和深层)为主要手段的。该工程深层地基土静载荷试验在井模中进行。井模设计按沉井的设计方法进行。为了防止逐段施工的井模下滑,井模制成如图所示的?型。
It is more difficult to test the effect of strengthening the gravel filling foundation after the consolidation method. An industrial plant in Panzhihua City uses a crushed energy with a click strength of 3200 KN·m and a reinforced concrete with a mean thickness of 15 m to test the effect of gravel-filled ground. It is a 120 kg heavy-duty dynamic penetration test and static load test (shallow and deep ) as the main means. The deep foundation soil static load test of this project is performed in the well mode. The design of the well pattern is carried out according to the design method of the caisson. In order to prevent the down-hole construction of the wells, the wells were molded into the type shown in the figure.
