山西潞能专用铁路工程线路由南至北跨越冲洪积阶地、丘陵和中低山区等多种地貌单元,其中特大桥和隧道的勘察是该项目的关键。勘察采用了地质测绘、现场调查、钻探、坑探、工程物探(超高密度电法)等多种原位测试方法、抽水试验及室内岩、土、水的物理力学性质试验等综合勘察方法,合理给出了复杂地层的合理地质参数建议值,确定了隧道围岩的等级划分,为该项目提供了可靠的设计依据。
Shanxi Lu special railway project from south to north across the alluvial terraces, hills and low mountains and other geomorphological units, of which the bridge and the tunnel survey is the key to the project. The survey adopts a variety of in situ test methods such as geological mapping, on-site investigation, drilling, pit exploration, engineering geophysical prospecting (ultra-high density electric method), pumping tests, and physical and mechanical properties tests of rock, Reasonable geological parameters of complex formations are reasonably given, and the classification of surrounding rock of tunnel is determined, which provides reliable design basis for this project.
