摘　　要：我国西北地域幅员辽阔,各种不良地质条件分布广泛,严重影响了电网基础设施建设进程.本文首先分析统计了西北各地区各类不良地质条件分布情况;然后,针对湿陷性、液化、盐渍土这三种典型不良地质条件提出了多种地基处理方案;最后,以通用设计A1-1方案为例研究了不同地基处理方案的适用性和经济性,计算出了各类不同深度不良地基的处理费用.可为电网类似工程提供可借鉴的技术建议.The northwest of China has a vast territory and various unfavorable geological conditions are widely distributed,seriously affecting the construction process of power grid infrastructure.This article first analyzes and calculates the distribution of various unfavorable geological conditions in various regions of the northwest of China.Then,a foundation treatment plan is proposed for three typical unfavorable geological conditions:collapsibility,liquefaction and saline soil.Finally,the applicability and economy of different foundation treatment schemes are studied by taking the universal design A1-1 scheme as an example,and the treatment costs of various kinds of bad foundations with different depths are calculated.This article can provide technical suggestions for similar projects in the power grid.
