Abstract

The invention provides a coastal complex stratum shield tunneling adaptability evaluation method. The method comprises the following steps of: S1, obtaining a final tunneling judgment matrix; S2, obtaining a tunneling weight matrix of the final tunneling judgment matrix obtained in the step S1 by using a genetic algorithm; S3, if the earth pressure balance shield tunneling machine is selected, executing the step S4, and if the slurry balance shield tunneling machine is selected, executing the step S5; the step S4 comprises: S41, obtaining an earth pressure balance shield tunneling membership matrix by using an earth pressure balance shield tunneling machine tunneling membership function in coastal complex stratum shield tunneling; and S42, calculating the tunneling fitness of the earth pressure balance shield tunneling machine according to the tunneling weight matrix obtained in the step S2 and the tunneling membership matrix of the earth pressure balance shield tunneling machine obtained in the step S41. According to the method, the coastal complex stratum can be tunneled in a better mode.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a method for evaluating the adaptability of shield tunneling in complex coastal strata. Background technique [0002] The rapid economic development in recent years has inevitably brought some negative problems, such as urban traffic congestion that needs to be solved urgently. As a means of relieving urban traffic congestion, the subway does not occupy surface space resources during construction, and the subway will divert some people who use surface transportation during operation. Therefore, more and more cities that meet the conditions for subway construction have begun to build subways. . [0003] At present, the methods of constructing subway tunnels in our country include open cut method, shallow buried underground method, mine method, shield method or several methods used together. Since subway tunnels are generally located in soft ground, and because the shiel...
