摘要
采用微型钢管桩和喷锚网联合支护结构体系,大大提高了基坑的整体稳定性和安全可靠性。监测结果表明,基坑边坡位移最大值为32 mm,最大沉降值为24 mm,符合规范要求;保障了整个基坑施工过程中基坑内工作正常进行和周围环境不受破坏。工程实例证明了该联合支护技术应用研究具有广阔的经济技术前景,为类似基坑工程支护的设计与施工提供了参考依据。
By using micro -steel pipe pile and spray anchor net formed the united surport structure system, the stability and reliability of the foundation was greatly enhanced. Monitoring results show that the maximum displacement of the pit slope is 32 mm, and the minimum value is 24 mm. Complied with the regulatory requirements, the safety of deep foundation during construction can be ensured and the normal work environment is protected. The united application of supporting technology has good prospects for economic and technology, and it can provide reference for the similar deep foundation construction.
