摘要
利用斜井作为施工通道成功解决了暗挖车站工作面少、出渣进料工效低、施工周期长等难题,但如何合理选址、避开重大风险、节约投资仍是暗挖车站斜井设计的一个关键性问题。以环线车站斜井方案设计为例,结合技术、经济、工期等因素综合分析,运用肯特指数法进行风险比较,并采用工程类比法对重大风险分析,研究复杂环境下的斜井方案设计,所得结论对类似工程有一定的参考价值及借鉴意义。
The inclined shaft as construction channel successfully resolved many problems in construction of underground station, just as the lack of excavation working face, the low efficiency of material transportation, the long construction period and so on. But how to site, to avoid risk and to save investment reasonably is still a key problem in design of underground station. This paper takes a certain inclined shaft design scheme as an example, evaluation method of Kent is applied in combination with technical, economic, construction period and other factors. The major risk is analyzing by the engineering analogy method, the construction design scheme in the complex environment is researching. All the obtained conclusions can be reference and guide to the urban tunnel.
