本文通过工程实例,对后注浆钻孔灌注桩单桩承载力的确定进行分析,运用原位静载荷试验数据和工程实例数据,说明后注浆钻孔灌注桩在保持传统钻孔灌注桩优点的同时,通过后注浆技术有效克服钻孔灌注桩单桩承载力偏低的缺点,在工程运用中显示出良好的技术性、经济性。
In this paper, through the engineering example, the bearing capacity of post-grouting cast-in-place bored pile is analyzed. The static grouting test data and engineering data are used to illustrate the advantages of bored cast-in-situ grouting At the same time, the post-grouting technology can effectively overcome the shortcoming of low bearing capacity of single pile of cast-in-place bored pile and shows good technical and economical performance in engineering application.
