Abstract

The invention discloses a horizontal geological survey layout method for deep buried underground caverns, comprising: conducting ground survey, forming a survey area geological background report and a geological survey implementation plan; conducting surface area geophysical survey, performing engineering geological division, and generating survey area engineering Geological zoning map to delineate geophysical abnormal zones; conduct long-distance horizontal drilling, and take core samples for indoor geotechnical tests to analyze the situation ahead of cavern excavation; pre-design cavern excavation support; conduct cavern tunnel excavation Excavation, advanced geophysical prospecting in the cave before excavation; deepening blast hole detection to judge the geological situation ahead; comparison with the advanced geophysical prospecting geological data, timely and dynamic adjustment of support design parameters; comprehensive detection results to build a 3D geological model of the underground cavern According to the detected geological conditions, the cavern support design and timely support modification are carried out to ensure the safety of cavern excavation. The invention can accurately survey the geological conditions of the underground cavern, and the construction time is short.

Description

technical field

[0001] The invention relates to the technical field of survey, design and construction of tunnels and underground engineering, in particular to a method for horizontal geological survey and arrangement of deep underground caverns. Background technique

[0002] In recent years, with the needs of my country's economic development, large-scale railways, highways, municipal tunnels, underground pipe galleries, water conservancy and hydropower tunnels, underground storage and other deep-buried super-long-span underground projects have appeared in large numbers, and their geological conditions are extremely complex. The uncertainty of unfavorable engineering geological problems has great constraints on engineering construction. The existing geological prospecting method is mainly based on conventional surface ultra-deep drilling, which is time-consuming, labor-intensive, and usually only one hole is arranged within a range of hundreds of meters, and the survey resul...
