Construction Risk

High speed railway tunnel have many uncertainty hazard factors in construction, at the stage of construction drawing design and during tunnel construction process. Taking no.1 tunnel in Xuefeng Mountain as a deep buried tunnel in the paper, tunnel construction risk source and main risk identification are analysis, main risk assessment during construction is recognized and reference for other similar projects is provided.

Empirical Design

The empirical design of tunnel 7 of the Jakarta-Bandung high-speed railway was based on the Basic Quality (BQ) system, which was the Chinese standard of rock mass classification. Due to the high uncertainty of a rock mass classification, comparative studies of rock mass quality and tunnel support systems based on other rock mass classifications are commonly required. The main objective of this research was to assess the rock mass quality and excavatability at the tunnel construction site and propose the tunnel support system based on three widely used methods, namely GSI, RMR, and Q-system. This study involved geological mapping, determination of surface and subsurface rock weathering, rock mass classification of drilling cores, and laboratory testing. The results show that the tunnel construction area consists of highly weathered volcanic and sedimentary rocks. The tunnel elevation consists of poor and extremely to very poor rock masses of sedimentary rocks. Hard digging is the optimum rock mass excavation method to use. Applications of rock bolt, wire mesh, and shotcrete are proposed for the tunnel support system.

Synthetic Evaluation

Because of its large scale, long cycle and complex construction, the high speed railway tunnel construction exists many uncertain risk factors which are random and fuzzy, that makes it difficult to do quantitative analysis by general research methods. A synthetic evaluation index system for tunnel construction risk of high-speed railway is established by analyzing the factors that influence high-speed railway construction, and the analytic hierarchy process is used to determine the weight of each stage factor. Based on the hierarchy of each factor, a model of three-stage fuzzy synthetic evaluation is proposed, the fuzzy sets method is used to determine membership function, and risk ranking is also classified. The proposed method is applied to a Tian jiashan Tunnel construction of Shanghai-Kunming (Hu-Kun) high-speed railway. The analysis results show that the method is reasonable and practical, and it will be taken as an example by other similar projects.
