矩形盾構(gòu)隧道施工風險定量評價與風險控制研究
[Abstract]:The site of this case belongs to the lithostratigraphic area of Ningbo, mainly Cretaceous purplish red siltstone and locally distributed late Yanshanian exhalation basalt. The Quaternary strata are relatively thick and stable, and the thickness is about 55-100 m. From the Middle Pleistocene to the Holocene, the strata are well developed. In the process of overall construction of shield tunneling project of Ningbo rail transit, the geological structure of the tunnel is more complicated and the natural environment is very bad. The existence of these factors causes the great risk in the implementation of the project. The shield tunnel project of subway has a wide range of social influence, huge investment, huge volume of construction engineering, complicated engineering process and many risk factors. Once encountered with dangerous situation, it will have a more bad effect. Therefore, it is necessary to prejudge, analyze and prepare the risk before the tunnel construction, so as to lay a firm foundation for the subsequent construction. In the course of case analysis, this paper has profound significance for risk control of Ningbo rail transit rectangular shield tunnel in construction process. In the process of concrete analysis and research, the main contents are as follows: (1) according to the basic research situation of risk management at home and abroad in recent years, The existing problems in wind control of shield tunnel engineering are summarized and sorted out. On this basis, combining with the theory of risk analysis, the feasibility of risk control and evaluation in specific cases is put forward. (2) through the basic definition of engineering risk, the basic risk classes and characteristics are briefly introduced. The related theories are discussed and analyzed from the aspect of risk management related to specific projects. (3) the fuzzy comprehensive evaluation system of construction risk of rectangular shield tunnel is established. The rectangular shield construction of the first phase underground civil engineering of Ningbo Rail Transit Line 3 and the first phase of Ningbo Rail Transit Line 3 is carried out by rectangular shield construction (Huangjiacun Station, Chenpodu Station ~ Huangjiacun Station, Chen Bodu Station, Chenpo Duyu Station, and Huangjiacun Station). The project of line opening excavation and rectangular shield tunneling in Jiang Shan's entrance and exit section, which consists of 2 stations and 2 sections, is a concrete example. The related risk factors are comprehensively analyzed and explored by means of analytic hierarchy process (AHP). On this basis, combined with the fuzzy evaluation and analysis method, put forward targeted technical measures. (4) on the basis of risk assessment, the rectangular shield and circular shield are compared and analyzed. At the same time, the paper analyzes the construction risk of entering and leaving the tunnel, crossing the special section and assembling the segment, and puts forward the quality assurance measures for the construction of Ningbo subway rectangular shield tunnel.
