摘要
结合软土深基坑工程实例,深入地了解桩间土体加固对双排桩支护结构变形性状的影响。采用双排型钢桩进行基坑支护时,前、后排型钢桩间土的加固可较好地保证前、后排型钢桩共同受力,且加固效果随前、后排桩间距的加大而增大,对型钢桩变形的控制具有重要的影响。同时,桩间土加固削弱了型钢桩与连梁的连接刚度对型钢桩变形的影响,可更好地保证基坑周边环境的安全。
Based on the specific projects, the influence of the deformation behavior of double -row -piles wall on the soil -reinforcement between the front and rear piles is analyzed. When the double - row steel piles are used and the soil - reinforcement between the front and rear piles is implemented, both the front and rear steel piles can perform better. With the increase of pile spacing, the reinforcement effect is more obvious which has an effect on the deformation control of steel pile. At the same time, the soil - reinforcement weakened the effect of the rotation stiffness between the steel piles and the coupling beams on the deformation of steel pile. Therefore, the soil - reinforcement between the piles can ensure the safety of surroundings around foundation pit better.
