天水地区第三系地层属于西秦岭甘肃群，梁家山隧道洞身穿越天水盆地第三系泥岩，为确定隧道围岩的地质特性，进行了泥岩样品的地球化学成分与矿物成分测试。将梁家山隧道泥岩的测试结果与天水秦安县下山剖面泥岩的结果进行对比分析和相关分析。结果表明：二者之间存在较好的相关性，能够描述梁家山隧道泥岩的地层岩性、区域地质背景及其演化等工程地质特性，为进一步研究天水盆地的物质组成、风化特征、沉积环境和构造背景提供依据。同时也为利用隧道工程修建研究相关地学问题提供范例和基础数据。

The tertiary formation in the Tianshui Basin is classified as Western Qinling, Gansu group. The Liangjiashan tunnel travels through the tertiary mudstone in the Tianshui Basin. In order to determine the geological properties of surrounding rock, the tests for geochemistry and mineral composition of mudstone specimen have been conducted. The test results from the Liangjiashan Tunnel were compared and correlated with the results from Xiashan section. It was indicated that the test results from the two sites correlate each other very well and can characterize the geological characteristics such as formation, tectonic background and its evolution of the mudstone in the Liangjiashan Tunnel. This can provide basic evidence for the studies on the compositions, weathering characteristics, sedimentary environment and tectonic background of the Tianshui Basin. This research can also be considered as a good example and supply the fundamental data for studies on related geological problems by using tunnel construction.

Key words: Mudstone, Geochemical analysis, Correlation, Multidimensional scaling, Geochemistry characteristics.
