| 摘 要： | 某工程桩出现质量事故,根据承载力和地质情况对桩基特点进行了分析,利用桩土共同作用原理进行加固,通过土参与承载补偿桩承载力不足.在构造上将基础与桩脱开,并设置褥垫层,通过有效技术措施促使桩土变形协调,从而达到桩土共同作用的效果.工程实例表明承载力和沉降均可以满足要求.

| Abstract: | Quality accident of pile happened,and the character of pile foundation is analyzed according to the geological condition and bearing capacity.The reinforcements which based on the principle of pile-soil interaction is adopted,soil supported load to compensate inadequate bearing capacity of pile.foundation and pile is separated in structure and cushion is applied,and the effective technical measure urge pile-soil distortion coordinate,then pile-soil interaction is achieved.furthermore,engineering project hol... |
