An intelligent real-time whole-process monitoring method for underground multi-level space, surface and underground

Abstract

The invention discloses a method for intelligent real-time whole process monitoring of surface and underground parts of an underground multi-level space. The method comprises (1) a multi-span multi-arch monitoring method, (2) a double-deck metro station monitoring method and (3) an underground multi-level space ground surface settlement deformation real-time monitoring method. The method improvesthe density and the observation frequency, knows the settlement change of the interior of the channel and the ground surface outside the hole at any time, provides security assurance for monitoring and measurement, eliminates hidden dangers of collapse in construction, guarantees smooth and safe construction, provides real-time monitoring data for operation and guarantees operation safety. The monitoring method realizes intelligent automatic measurement, has high measurement accuracy, is installed simply and does not influence the construction.

Description

technical field [0001] The invention relates to the field of underground space, in particular to an intelligent real-time whole-process monitoring method on the surface and underground of multi-level underground spaces. Background technique [0002] With the continuous development of my country's economy and society, the scale of transportation infrastructure construction has gradually expanded, and the number and mileage of tunnels have gradually increased. As of 2010, the total length of my country's built railway tunnels exceeds 7,000km, road tunnels reach 5,000km, and subway lines reach 1,400km. It is estimated that by 2020, my country will also plan to build 5,000 tunnels with a total length of more than 9,000 kilometers. my country has become the country with the most, most complex and fastest-growing tunnels in the world. [0003] Tunnel construction, especially the excavation process, will produce surrounding rock disturbance effects, which will cause tunnel vault ...

AI Technical Summary

Problems solved by technology

This measurement method has the following disadvantages: 1) It requires technicians to go to the site for manual measurement. Not only is the on-site operation complicated, time-consuming and laborious, but also human factors have a greater impact on the measurement accuracy; 2) Urban tunnels are usually built along the main road. The traffic on the road is heavy, the environment is complex, there are many influencing factors, the measurement site is narrow, and field measurements are often required at night, and the light is weak, resulting in low reliability and sensitivity of the measurement; 3) each section only measures a limited number of points, It is difficult to accurately reflect the deformation state of the entire section; 4) File management and manual calculation are usually used to process on-site monitoring data, which cannot realize database management, sharing and original data traceability, resulting in low analysis efficiency and data authenticity cannot be guaranteed

However, the above-mentioned monitoring equipment has disadvantages such as high cost and difficult installation, and is rarely used in actual projects.
