Study on the Smoke Evacuation and Safety-Evaluation of Oversized Shield Machine in Tunnel Drilling

Abstract:

Based on the data of the extra large diameter and extra distance of drilling of the Shanghai Yangtze Tunnel Highway, the paper introduces various fire scenarios under shield construction, and examines the distribution of various tunnel fires according to the actual circumstance of tunnel construction, patterns of smoke change of various fire circumstances; The thesis also provides significant measures and time for evacuation, and the features of fire expansion and smoke circulation in different fire situations, It compares fire expansion and smoke extension in different fire situations, analyzes patterns of fire expansion and smoke extension in different measures of fire prevention and their impact on the consequences of fire. Meanwhile, the thesis evaluates the effect of fire prevention, and explores some basic principles and safety measures for evacuating performance and fire rescue, crew safety and efficiency according to the temperature in the tunnel, pressure and smoke extension with fire
