西宁黄土状盐渍土作为回填材料的研究
摘要:通过对西宁地区黄土状盐渍土地基的分布、工程性质特点及其对建筑物危害的调查,分别从黄土状盐渍土的湿陷(溶陷)、盐胀和腐蚀性三大特点出发,对西宁黄土状盐渍土地基中回填用料土含盐量的变化对地基土性质的影响作了一些试验研究,提出了一些观点,通过实践取得了一定的社会效果和经济效益。
Abstract:Based on the investigation of distribution of the loess-like saline soil foundations in Xining, engineering characteristics and the damages to the building, respectively, from three characteristics of the settlement by soaking, salt expansion and causticity of the loess-like saline soil, the author research into the effects on the nature of the foundations from the changes of salinity in the backfill in the loess-like saline soil foundations in Xining. Some of the points raised by the practice has achieved a certain degree of social effects and economic benefits.
