摘要
结合佛山市三水区某工程的实际情况,提出了高压旋喷+压力注浆固结法处理桩基下持力层溶洞的方案,并阐述了具体的施工技术与设计方法,通过静载试验表明,处理后桩基的竖向承载力满足设计要求。
Combining with the actual situation of a engineering in Foshan Sanshui district,this paper proposed the scheme of high pressure jet grouting ＋ pressure consolidation treatment of pile foundation under bearing layer karst cave,and elaborated specific construction technology and design method,through the static load test showed that the vertical bearing capacity after pile foundation treatment met the design requirements.
