摘　　要：昔格达地层因在形貌和工程性质上的特殊性和破坏作用的严重性,引起了工程界的广泛重视。在前人研究的基础上,使用水玻璃溶液改良昔格达土,并进行了一系列室内土工试验,文中对于经水玻璃改良后的昔格达土的基本物理性质、力学特性等进行了对比分析。结果表明,用水玻璃改良昔格达土是可行的,其最佳掺量为5%。Xigeda Strata has attracted wide attention from the field of engineering due to its particular topography and engineering property and severe destruction action. On the basis of former research, this paper carries out a series of geotechnical tests for Xigeda soil improved with solution of soluble glass and makes contrast analysis on the basic physical characteristics and mechanical property of improved Xigeda soil. The result indicates that it is feasible to improve Xigeda soil with soluble glass, with the optimum mixing proportion of 5%.
