为了满足社会的需求,对地下空间做到最大限度的利用,就要求深基坑工程向横向、纵向两方面不断的扩张,这就加大了支护系统的设计难度,如何做到最稳定、有效的支撑成为了首先需要解决的问题。如果稍有疏忽,就会造成地面塌陷,上层建筑倒塌的严重后果,因此在挖掘基坑前,应详细的做好土质勘探工作,严谨地做好书面记录,并针对特殊气候可能导致的土质变化情况设立预案。
In order to meet the needs of the society and make maximum use of the underground space, it is required that the deep foundation pit project should be continuously expanded both horizontally and vertically, which increases the difficulty of design of the support system and how to achieve the most stable, Effective support has become the first problem to be solved. If the slightest negligence will result in the collapse of the ground and the serious consequences of the collapse of the superstructure, we should do a good job of soil exploration work in detail before digging the foundation pit, rigorously make written records and address the possible changes in the soil due to the special climate The situation set up plans.
