摘要
文中结合实际工程,通过采用双排支护桩+预应力钢管斜撑+坑内加固组合的施工技术,有效解决了深基坑支护结构中成本高、安全性能较低的问题,同时节约了施工成本,提高了基坑支护体系的稳定性。这说明提前施加反作用力,可发挥基坑底土体和基础的承载力,及时控制变形情况,保障施工质量。
Combined with practical engineering,this paper effectively solves the problems of high cost and low safety performance in the deep foundation pit support structure by adopting the construction technology method of double-row supporting pile+prestressed steel pipe diagonal brace+in-pit reinforcement,and at the same time saves the construction cost and improves the stability of the foundation pit support system.By applying the reaction force in advance,the bearing capacity of the soil and foundation at the bottom of the foundation pit is brought into play,and the deformation is controlled in time to ensure the construction quality.
