The Application Of Anchor-bolt Seismic In Mountain Building And Site Stability Technology Research

China is a country with frequent earthquakes.Earthquake disasters are unprecedentedly damaging to building damage and personal injury.At the same time,with the development of China’s economy and society,the population is increasing and the land supply for housing construction is becoming increasingly scarce.In the case of mountain construction,the mountainous building is characterized by the non-buried depth of the basement in the soil.During the construction process,in addition to the remediation work of the site to ensure safety and stability,it is necessary to consider the foundation of the building Seismic action.Based on the current seismic theory,site stability and bolt mechanism review of development theory and on the basis of summing up,by combining the Zirui garden project around and improve the stability of technology site seismic analysis of horizontal earthquake resistance using bolt in mountainous buildings,summarizes the design and construction experience,and provide the reference for similar engineering.The main work and innovation of the paper are as follows:(1)Through the current seismic theory of the building structure,the safety and stability of the site slope,the dynamic performance of the bolt support and the mechanism of action,it is proposed that the seismic fortification must be considered from the perspective of site safety and stability;(2)According to the structural form and site characteristics of the actual project,a new type of viaduct double-row pile retaining wall structure is adopted,and the finite element software SAP2000 is used to analyze the mechanical properties of theretaining structure and check Analyze the overall stability of slippery slope,determine the slope safety and stability of mountain construction site;(3)The dynamic performance analysis formula of the floor bolting structure is deduced based on the classical mechanics method.The dynamic performance and stiffness coordination performance of the floor bolts are calculated,and the bolt system is designed to provide the horizontal resistance to balance the earthquake Of the horizontal force,for the construction of anti-dumping overall stability to provide the level of reaction;(4)Based on the design experience and the requirements of the construction process,the design of the project site support scheme and the prestressed anchor rock seismic design are completed.Through the later tests and tests,the obtained data are analyzed and verified,indicating that the stability and anchor of the mountain building site The Feasibility of Anti-seismic Technology.
