摘要:
强夯地基处理技术是一种常见、有效的地基处理方法,但由于其施工时的噪音、振动等对周围建筑物和环境的影响而限制了它的作用.通过对某高速公路强夯地基工程的实践,对不同夯击能下强夯地基处理施工时所产生的地面振动进行了现场监测,经过对这些实测振动资料的深入分析,认为当强夯所引起的地面振动加速度衰减到0.1g时,对建筑物几乎没有危害.同时得出当强夯夯击能为1.5,2.0,2.5和3.0 MN·m时,其对构筑物的安全距离分别为14,17.5,18.7和19.5 m.
Abstract:
Dynamic Compaction is a well-known and effective method in ground improvement. The application of this method is often restricted because of its noise, vibration and construction environment. According to the test and supervision of the practice of a dynamic compaction project in expressway, the testing data of ground shake are analyzed in detail. The test results show that the building will be safe when the ground acceleration is caused by dynamic compaction attenuated to 0.1g. The safe distance is 14, 17.5, 18.5 and 19.5 m, respectively under the dynamic compaction of 1.5, 2.0, 2.5 and 3.5 MN·m.
