摘要
Abstract
The geotectonic structure in the region where the geotechnical investigations were made is a terrain joining the Yangtze Platform and the South China Platform and is the Panjiang large and multi-stratum mat structure of upthrust and nappe,located in the southwest of Guizhou. With the action of Banchang upthrust,the faults are crisscrossing and the superimposed folds are developed. The character of lithological development is mainly represented by the mudstone, sandstone, marlite and limestone of the Triassic System and the limestone of the Permian System. The lithological characters vary greatly with developed peculiar rock-soil and unfavorable geology,making the engineering geologic conditions on site extremely complex. The major existing geologic problems are the stability and differential settlement of the soft soil subgrade and the slope stability.关键词
