随着社会经济的飞速发展,我国的土木工程也在高速发展中,多层建筑、高层以及超高层建筑的普及,因此对基坑工程的要求也越来越高,这是对工程施工的巨大考验。在目前的很多土建工程的施工过程中,大都采用支护技术来增强基坑边坡的稳定性,但是对于基坑深度较深,传统的钢板桩加井点降水的支护方式已经满足不了深基坑的要求了,因此本文对不良地质条件下的深基坑施工技术作简要的说明。 With the rapid development of society and economy, civil engineering in our country is also developing rapidly, and multi-storey buildings, high-rise buildings and super-tall buildings are popularized. Therefore, the requirements for excavation engineering are also getting higher and higher, test. In the current construction of many civil engineering projects, most of the support technology is used to enhance the stability of the foundation pit slope, but for the deep foundation pit, the traditional support methods of sheet pile plus well point precipitation can not satisfy the deep Therefore, this paper gives a brief description of the construction technology of deep foundation pit under adverse geological conditions.
