| 摘 要： | 在多年冻土区,由于特殊的冻土工程地质条件带来的冻土问题,是铁路建设及维护面临的难题之一.为评价铁路沿线冻土工程地质条件,从分析影响冻土工程地质条件特征的两大因素冻土热稳定性和自然环境条件出发,结合现场勘探资料,采用突变级数法建立了可量化的冻土工程地质评价模型并划定评价等级,评价结果S分为5级:恶劣(S≤0.77)、较差...

| Abstract: | The engineering problem caused by the special geological conditions in permafrost regions will be the main factor that affects the stability of the railway construction.In order to solve the problem,it is necessary to explore the engineering geological conditions along the railway and then give an evaluation that can be used as the guidance in engineering construction on permafrost regions.More than half of the recently built 142 km long Chai Mu Railway(CMR) in northern Qinghai Province,China travels across... |
