甬台温铁路进一步提速的可行性研究

Research on the Feasibility of Further Speed-raise of Ningbo-Taizhou-Wenzhou Railway

研究目的:参照同类建设标准项目的运营实践,结合项目工程特点和地质特征,对影响提速的各项关键因素进行分析,提出解决措施和需要深入研究的问题,论证进一步提速的可行性。研究结论:从甬台温铁路建设标准和各项基础设施及配套工程技术措施分析,本线进一步提速在技术上是可行的。通过局部调整道床厚度、变更道砟等级,分析路基工后沉降并采取补强措施后可实现开通运营250 km/h的需求。运输组织和各项工程技术总体上可适应远期提速300 km/h要求,但尚需对运输组织模式、信号区间行车布点等技术进行深入研究和完善。

Research purposes： Through reference to the operation practice of similar railway and based on the engineering and geological characteristics of Ningbo - Taizhou - Wenzhou Railway, all influence factors on speed - raise of the railway are analyzed, the measures to be taken and the problems to be studied are offered and the feasibility of further speed - raise of the railway is verified. Research conclusions：Through analyzing the construction standards and technical measures for various infrastructures and auxiliary projects, to further raise the railway speed is feasible. By adjusting partial ballast thickness, improving the grades of ballast and reinforcing the subgrade, the goal of running 250 km/h train can be achieved. On the whole, transportation organization and various engineering technology can adapt to the requirement of running 300 km/h train in future, but transportation pattern and signaling system should be further studied and perfected.
