摘要
Abstract
Tianhe Park Station of Guangzhou Metro Line No.11 and No.13 is located in Guangzhou urban center, where dense buildings, complex designing and construction conditions and higher environmental requirements greatly constrain the design of the tie line. Based on the analysis of the problems in the original tie line scheme, two optimization alternatives are put forward to increase the curve radius to adapt to the conditions of shield construction and to decrease the curve radius to reduce the gushing water and sand mining risk. Then a comprehensive analysis of designing scheme is conducted in terms of the line condition, surrounding environment, engineering risks and project investment. Finally,a tie line design scheme with a radius of 200 m is recommended. The research method and conclusions provide some references for the planning and design of metro tie line in urban center. The factors that should be taken into consideration in the planning and design of metro tie line in urban center are summarized to ensure that the final recommended engineering scheme is feasible.关键词
