Improvement method of sulfate salinized soil used as roadbed filler
The invention relates to an improvement method of sulfate salinized soil used as roadbed filler, which relates to the field of highway roadbed construction, and comprises the following steps: step 1, analyzing the property of salinized soil; 2, coarse aggregate improvement: carrying out coarse aggregate improvement according to the salinized soil property analysis in the step 1 to obtain the salinized soil subjected to primary improvement until the maximum dry density, the optimal water content, the CBR and the resilience modulus of the salinized soil subjected to primary improvement meet the requirements; and 3, fine aggregate improvement: performing fine aggregate improvement on the salinized soil subjected to primary improvement in the step 2 to obtain secondary improved salinized soil until the salt content, CBR and salt expansion performance of the secondary improved salinized soil meet the requirements, thereby obtaining the improved salinized soil. According to the method, the sulfuric acid salinized soil used as roadbed filler in the Xinjiang region is subjected to targeted analysis and then subjected to primary coarse aggregate improvement, secondary fine aggregate improvement is performed after the primary improvement is completed, and various construction design specifications in the Xinjiang region are met after the secondary improvement.
本发明涉及一种用作路基填料的硫酸盐渍土的改良方法，涉及公路路基施工领域，包括如下步骤：步骤1，对盐渍土性质分析；步骤2，粗集料改良：根据步骤1对盐渍土性质分析进行粗集料改良，得到一次改良的盐渍土，直到一次改良的盐渍土的最大干密度、最佳含水率、CBR及回弹模量符合要求；步骤3，细集料改良：对步骤2中一次改良的盐渍土进行细集料改良，得到二次改良的盐渍土，直到二次改良的盐渍土的含盐量、CBR、盐胀性能符合要求，得到改良的盐渍土。本发明通过对新疆地区用作路基填料的硫酸盐渍土进行针对性分析，后对其进行粗集料一次改良，一次改良完毕后进行细集料的二次改良，二次改良后满足新疆地区的各类施工设计规范。
