一、概述强夯法是将几十吨重(一般为8～30吨)的重锤,从几十米高(一般为6～30米)的高处自由落下,对土进行强力夯实,以提高其承载力,降低其压缩性的一种地基加固方法。这是在重锤夯实法的基础上发展起来的一项新技术。过去的重锤夯实法锤重不大、落距不高,主要是考虑锤对土的压力,往往影响深度不大,效果不很理想。而这种方法是用很大的冲击能(一般为50～800吨米)使土中 I. Overview The Qiangyan method frees dozens of tons (usually 8 to 30 tons) of heavy hammers from a height of several tens of meters (typically 6 to 30 meters) to strongly consolidate the soil. A ground reinforcement method to improve its bearing capacity and reduce its compressibility. This is a new technology developed on the basis of heavy hammer compaction. In the past, the hammer weighting method was not heavy, and the drop distance was not high. It was mainly to consider the pressure of the hammer on the soil, which often had little effect, and the effect was not very satisfactory. This method uses large impact energy (usually 50-800 tons of rice) to make the soil
