摘要
以青岛地区某典型"土岩组合"基坑为例,对该问题进行分析研究,利用支护软件对该工程进行支护设计,在设计中加大锚杆倾角,并结合坑内留台等技术措施,通过现场监测,证明这些措施有效地限制了土体位移,保证了桩锚支护系统稳定安全,可供类似条件下的支护工程借鉴.
A typical soil-rock composite pit in soft soil areas in Qingdao is designed and constructed according to the software of pit-retaining. In addition, the anchor of large angle combined with platforms inside is adopted in this design. As a result, the monitored horizontal displacements are all in the standard limit of design. It proves that this technology can effectively limit the displacement of the soil and ensure the steadiness and the safety of the supporting system. Therefore, it can be used as a reference for similar projects.
