摘要
文章以某建筑工程为例,在了解施工现场土层分布特征的基础上,提出施工控制要点,研究了深基坑支护施工技术,包含开挖方法、土钉墙及喷射混凝土、预应力锚索及腰梁的具体施工方法,制定深基坑施工监测方案,通过地面最大沉降量和坡顶水平位移等监测数据检验深基坑支护施工效果。
Taking a construction project as an example,based on understanding the soil layer distribution characteristics of the construction site,this paper puts forward the key points of construction control,studies the construction technology of deep foundation pit support,including excavation method,soil nailing wall and shotcrete,concrete construction method of prestressed anchor cable and waist beam,and develops the construction monitoring scheme of deep foundation pit.The effect of deep foundation pit support construction is tested by monitoring data such as maximum ground settlement and horizontal displacement of slope top.
