摘　　要：为了比较刚性桩和柔性桩的荷载传递规律,在温州地区选择了钻孔灌注桩和水泥搅拌桩进行静荷载试验。试验前在钻孔灌注桩桩身埋设了钢筋应力计,在水泥搅拌桩桩身埋设了振弦式应变计。在静荷载试验过程中同步检测传感器的变化情况,根据试验成果对两种不同类型桩进行对比分析,得出一些有益的结论,供工程设计施工人员参考。In order to compare with load transfer mechanism of rigid pile and flexible pile,static load test of cast-in-place pile and cement mixing pile is carried out. Stress meters are embedded along cast-in-place pile shaft and strain meters are embedded along cement mixing pile shaft .Sensors are monitored in the process of static load test. Different types of piles are analyzed and obtain some meaningful conclusions good for design and construction are drawn.
