| 摘 要： | 含盐地层作为一类特殊的工程地质体，其工程性能具有易变性，各向异性以及冻胀性等特点，由于含盐地层中含有易溶盐，土体的物理力学性质因环境因素如气修、地下水和受力性质的改变而发生明显的变化，而且对修建于其构筑物具有腐蚀性，本文以穿越罕尔汗盐湖的青藏铁路路基基底地层和盐渍地为研究对象，对盐湖岩盐和周边地区盐渍土层清土层的工程地质性质进行研究，通过对含盐地层基本工程性能的系统研究，归纳出在通过含盐地层时，铁路对含盐地层基本工程性能的系统研究，归纳出在通过含盐地层时，铁路工程施工应该注意的事项，以保证工程项目的长期稳定性。

| Abstract: | Salt bearing strata are widely distributed in western part of China and these strata can be treated as special engineering materials for their changeability, anisotropy and capability of frost heave. The strata can cause much trouble for foundation construction. During the implementation of western China development project, these strata may be encountered or even be used as foundation bedrock. Due to the soluble salt in the soil mass, the mechanical characters of the soil can change obviously when environmental conditions such as weather, groundwater and stress state are altered. The authors made a thorough study on engineering properties of salt bearing strata in Qinghai Tibet railway, the results obtained can be used to insure long term stability of engineering projects built in salt bearing strata. |
