Analysis of water inflow and optimization of engineering transition section in undersea tunnel
摘要
Abstract
The undersea tunnel is located in a state of high confining pressure and high water pressure,and there is unlimited water supply above it.Seepage and water inrush are easy to occur during the construction process.Therefore,adjusting the corresponding construction plan based on the prediction results of water inrush can reduce the probability of water inrush.Based on the Shantou Bay Undersea Tunnel project,this paper compares the results of water inflow in various tunnels from the analytic formula and gives the most applicable prediction formula for the project.At the same time,the results are used to carry out orthogonal test,and the three factors affecting the stability of the transition section are analyzed,the order of every factors affecting the two indexes of differences of crown settlement and water inflow is determined.The results show that the result from the Macastor Analytic Formula is more safe and close to the engineering survey data.It is also found that the total length of the engineering transition section has a significant influence on the stability of the interface of surrounding rock,but the influence of excavation method and excavation progress on it is not significant.When the length of the transition section is about 10 m,the transition section has a good effect on improving the stability of the interface of surrounding rock.When the length of the transition section is greater than 10 m,the improvement effect is not significant.关键词
