Title:
OPTIMIZATION METHOD FOR STARTING END REINFORCEMENT SCHEME OF SHIELD TUNNEL
Document Type and Number:
WIPO Patent Application WO/2022/236955
Kind Code:
A1
Abstract:
The present invention provides an optimization method for a starting end reinforcement scheme of a shield tunnel, comprising the specific steps: obtaining shield tunnel engineering data and the temperature change curves of temperature measurement holes; according to the shield tunnel engineering data, separately constructing a heat convection numerical model and a hydrothermal coupling numerical model; after performing numerical simulation on the described two models, separately obtaining a first temperature change curve and a second temperature change curve; comparing and analyzing the temperature change curves of the temperature measurement holes with the first temperature change curve and the second temperature change curve, so that the influence condition of seepage on the development pattern of a temperature field can be obtained; and finally, optimizing the freezing scheme of an existing shield tunnel according to the influence condition of seepage on the development pattern of the temperature field. Therefore, it is ensured that the shield tunnel can be safely used.
