Dynamic feedback multi-pilot tunnel mechanical tunneling construction method for small-clear-distance-oblique-crossing super-long-span high-speed railway tunnels

Abstract

A dynamic feedback multi-pilot tunnel mechanical tunnelling construction method for small-clear-distance oblique-crossing super-long-span high-speed railway tunnels is disclosed. Multi-source monitoring data from the surrounding rock, the new tunnel, and the existing tunnel structure are collected in real time and transmitted wirelessly to enable dynamic feedback for the design and construction of the new tunnel while taking the operating conditions of the existing tunnel into consideration. This method achieves the dual safety objectives of ensuring both the safety of the existing tunnel and the construction safety of the new tunnel.
