冻土路基热稳定性研究现状分析与发展趋势展望

The Present Situation Summary and Future Direction Forecast of the Thermal Stability Research of Frozen Soil Roadbed

随着西部大开发的深入推进,大量的工程将集中在宽度不足10km的青藏工程走廊的范围内,工程之间的相互作用对冻土路基的热稳定性将造成重要的影响。本文通过冻土路基设计思想、热稳定性评价标准、研究方法与结论,热稳定性提升措施四个方面对冻土路基热稳定性的研究现状进行了总结,并对其未来研究的方向和趋势进行了展望。以期为相关科研人员和工程人员提供一个相对全面的文献基础。

Accompany with the further propulsion of China Western Development,a lot of constructions will locate at the range of the Tibetan engineering corridor which only has a width less than 10 km. The interactions of these constructions will affect the thermal stability of constructed frozen soil roadbeds significantly. A lot of researches works have done to study the thermal stability of the frozen roadbed,but there almost no paper was given a summarization of these achievements. Based on this situation,the present status of the thermal stability researches of frozen soil roadbed,including the design thoughts,evaluation criterion,research method and conclusions and reinforce measures,is analyzed in this paper. And,the future study direction and issues are forecasted. This work is expected to provide a comparatively overall literature basis for the relative researchers and engineers.
