The Study of Optimal Design Method for Safe Monitoring in Tunnel

Article Preview

The deformation tendency and order of magnitude for surrounding rock, expressing the state of rock mass, always change the construction schemes and treatment measures. The monitoring is the most important guarantee for safety construction and operation in civil engineering. However, due to the unsuitable monitoring sections and equipments selected, the budget remains stubbornly high. Most of business owners just carry out some of them or even give up the monitoring. This brings enormous hidden trouble to construct. Based on the Doupengshan highway tunnel, the optimal design method for safety monitoring was studied by comprehensive analysis of the geological conditions, the results of numerical modeling and monitoring data. The main aim of monitoring is to obtain the most poor condition information rather than all of them. It’s best to employ different type of monitoring instruments in order to verify results each other. That is to say, the monitoring of internal force or displacement can take the place of the convergence monitoring every two sections. The new monitoring design saves the budget 20% than origin one. The research result will guide the monitoring design for similar engineering.
