Abstract：Research purposes: Chehe station lied in the gentle slope pass across 21 natural gulleys. It is discovered that the slope soft soil is distributed in a majority of gullet's when excavating and testing filling. Therefore，it is necessary to find out the forming causes，range，thickness and engineering property of the soft soil for providing basis to design.
Research methods: Based on research conclusions of mountainous slope soft soil of such railway projects as NeiKun and ShuiBo，etc. designed by our institute，the research is carried out by comprehensive exploring measures including test pit , drilling ,static cone penetration test, light-type dynamic cone penetration test and tests.
Research results: Soft soils with different depth are distributed in 16 gullet's at Chehe station，of which the common characters are soft in quality of soil , various in composition ,uneven in distribution and property and mingled with plenty of rock fragments. At last the foundation is consolidated by the heavy-tamping broken stone piers.
Research conclusions: Particular geohydrologic environment formed by stratum structure provide conditions for forming of gentle slope gullet' soft soil. The treatment measures of slope soft soil include drainage，foundation replacement and retaining. According to the construction results，it is east' to treat the slope soft soil at the Chehe station with heavy- tamping replacement method and its effects are obvious.
