摘要
武汉某工程基坑支护采用无栈桥的支护桩内支撑方案,由钢筋混凝土灌注桩、格构柱、钢筋混凝土支撑构件和冠梁组成支撑系统,并采用了钢结构换撑技术。监测数据分析表明,该基坑支撑体系安全可靠,支撑效果良好。
The foundation pit support of a project in Wuhan adopts the support structure of the support pile without the trestle. The reinforced concrete pouring pile, the lattice column, the reinforced concrete support member and the crown beam form a support system, and the steel structure changing support technology is adopted. The monitoring data analysis shows that the foundation pit support system is safe and reliable, and the supporting effect is good.
