深基坑土方开挖是一个复杂的地质工程问题,它既涉及到基坑的自身强度与稳定性,又包含了地质环境和社会影响问题。在基坑土方开挖过程中,除了要保证基坑的安全,使坑内和坑外的各种工程顺利施工,还要保证相邻建筑物和地下管线等设施的安全。根据施工经验,分析了深基坑土方开挖施工中常见问题及其处理方法的关键技术,对深基坑施工时突发事件的处理具有非常积极的借鉴意义。
Earth excavation of deep foundation pit is a complex geological engineering problem, which not only relates to the self-strength and stability of foundation pit, but also includes the geological environment and social impact. During excavation of foundation pit earthwork, in addition to ensuring the safety of foundation pit, all kinds of works inside and outside the pit should be constructed smoothly, and facilities such as adjacent buildings and underground pipelines should also be ensured. According to the construction experience, this paper analyzes the common problems in the earthwork excavation of deep foundation pit and the key technologies of its treatment. It has a very positive reference for dealing with emergencies in deep foundation pit construction.
