摘要
振动碾压、冲击碾压通常用于加固软弱地基,目前在碳酸盐岩地区的相关应用研究还较少。结合某地基处理工程,选择振动碾压及冲击碾压施工工艺对碳酸盐岩块石填方地基进行处理研究。通过现场取样、荷载试验、瑞雷波,以及沉降观测等多种手段对加固效果进行检测,结果表明两种施工工艺对碳酸盐岩块石地基的处理均能够满足上部建筑物的承载力需求,但冲击碾压的效果好于振动碾压。对于块石填料的加固效果检测时建议以沉降检测、取样测试为主,辅以一定数量的荷载试验。
Vibration rolling and impact compaction are usually used for reinforcement of soft foundation.The applied research is still less in carbonate rock area now. This paper studies on relevant project that it chooses the vibration rolling and impact compaction to reinforce carbonate rock foundation in Liupanshui.Through sampling in site,loading test,Rayleigh wave,and settlement observation to detect,the result shows that the reinforced foundation can meet the needs of the upper building＇s carrying capacity. For the reinforcement effect of the block stone filler,it is suggested that the settlement test,the sampling test,and a certain amount of load test are good.
