概述了西宁地区三级阶地以上盐渍土的分布。黄土状盐渍土湿陷、溶陷机理,通过测定(湿陷+溶陷)系数,利用差减法确定湿陷和溶陷所占的比例,分析对比后得知西宁地区南山段盐渍土湿陷性占主导地位;同时提出西宁地区盐渍土工程地基处理要以防治结合、综合治理的原则,并采取相应的防水、地基基础和结构措施。
The distribution of saline soil above the terraces in Xining area is summarized. The collapsibility and dissolution mechanism of loess salty soil were determined by measuring the coefficients of (collapsibility + trapping), and the difference between the proportion of collapses and traps was determined by difference subtraction method. After comparison and analysis, it was found that the wettability of saline soil in Nanshan section of Xining At the same time, it puts forward the principle that the saline soil engineering ground treatment in Xining should be combined with prevention and treatment and comprehensive management, and take the corresponding waterproof, foundation and structural measures.
