新疆几种特殊土的工程地质特征及对工程建设的影响

The Engineering Geological Properties of Several Special Earth in Xinjiang and Their Influence to Engineering Construction

新疆地处严寒和干旱地区，在这种环境条件下，生成一些特殊成分结构及工程地质性质的土，包括湿陷性黄土、膨胀土、淤泥及淤泥质软土、盐渍土、冻土、填土、沙漠土等。这类土具有显著的地区性特征，会出现特殊的工程地质问题，给工程建设带来一定危害。为保证建筑物安全，从研究这类土的特殊性出发。

Several building earths have been studied in this paper.They have great influence on engineering construction.These kinds of earth possess remarkable regional properties which will bring harmful effect to engineering construction.For the sake of safety,the present paper puts forwards ways of evaluating these sorts of earths used in contruction and also states corresponding opinions of how to treat the problem.\;
