- Conclusions as following have got through test study : ( 1 ) when impact compaction technology is applied to treat collapsible loess subgrade , the effect depth may be treated generally can not override 80 cm and impact compaction pass is optimum at 30 times . ( 2 ) for stratified impact compaction of subgrade , when compactness of each level reaches codeslstandards loose laying depth of 80 cm fits 40 impact compaction pass is the optimum combination of subgrade construction . when average compactness in each level reaches codeslstandards loose laying depth of 80 cm fits 30 impact compaction pass is the optimum combination o ( 3 ) the quality control method may request impact compaction pass as the main control index and at the same time the final division settlement is less than 10 % of total settlement as large area subgrade is constructed
通过试验研究主要得出如下认识：冲击压实技术处理湿陷性黄土地基时，其有效处理深度一般不超过80cm ，冲压遍数以30遍左右为宜；对路基分层冲压，在要求土体中各点压实度均达到规范要求时，路基冲压最佳组合为虚铺厚度80cm 、冲压40遍；在只要求土体平均压实度达到规范要求时，路基冲压最佳组合为虚铺厚度80cm 、冲压30遍；大面积施工时，质量控制方法可按照在以冲压遍数作为主要控制指标的同时，要求最后10遍分计沉降量小于累计沉降量10 ；在施工单位自己购置冲击压实机情况下，与传统施工相比较，冲击压实技术是一种既能节约资金又能大量缩短工期的施工方法。
