摘要
结合重庆力帆中心临江深基坑工程,介绍了门形抗滑桩结合高压旋喷止水帷幕支护技术的应用。利用有限元分析及结合现场实际监测,得出了门形抗滑桩支护在临江软土基坑中可以较好控制基坑侧向变形,门形抗滑桩结合高压旋喷止水帷幕能很好屏蔽江水的渗透,确保了周边构筑物的安全及基坑内施工的安全。严格控制关键工序,对确保施工质量至关重要。
Based on the river-side deep foundation excavation of Chongqing Lifan Center, this paper introduces the application of portal structure anti-slide pile combined with high-pressure jet grouting waterproof curtain supports. Using finite element analysis and field monitoring, it is concluded that the portal structure anti-slide pile can control the lateral deformation of soft foundation excavation effectively, and the portal structure anti-slide pile combined with high-pressure jet grouting waterproof curtain supports can stop the penetration of river water well, and ensure the safety of the surrounding structures and the safety of construction in foundation excavation. Strict control of key working procedures is critical to ensuring the construction quality.
