一、前言强夯法加固地基是七十年代发展起来的软基加固方法,多用于处理深层地基。对2米左右表面土强夯后一般多松动,而建筑工程处理多数要求在浅层,地基表层侧向约束很小,夯击能过大反而不利。所以我们认为处理建筑物的浅层地基选用小能量连续强夯法比较适宜。从小能量夯击着眼,将强夯法一点多击改为一点一击,多遍跳档改为连续强夯等施工工艺。 1980年年底以来,我院曾对落房土杂土地基、钢渣杂土地基,与较低含水量的素填土地基,均采用小能量连续强夯法进行工程
I. Preface The strengthening of foundations by the strong ramming method was a soft ground reinforcement method developed in the 1970s. It was mostly used to deal with deep foundations. After about 2 meters of surface soil is generally more loose, and the majority of construction engineering requirements in the shallow layer, the surface of the surface lateral constraints are small, slamming can be too large and unfavorable. Therefore, we believe that it is more appropriate to use the small energy continuous dynamic compaction method to deal with the shallow foundations of buildings. From the small energy sniper slamming, the smashing method was changed to a one-on-one attack, and the multi-pass skip was changed to continuous smashing and other construction processes. Since the end of 1980, our institute has used the small energy continuous dynamic compaction method to carry out the project on the falling house soil and steel slag mixed ground, and the low water content of the plain fill foundation.
