摘要
引入综合分析法,对铁路工程注浆加固中浆液对周围水环境的影响展开研究。首先,分析注浆巷道返修时浆液的扩散范围,从而确定注浆加固过程存在的不足,并设计三步注浆工艺。在此基础上,将周围水环境质量划分五个等级,设定单项组分和多项组分评价指标,利用综合评价法科学地评价周围水环境水质情况,确定不同等级下的评价分值。再依据铁路工程注浆加固前后水样各指标参数值,按照水环境质量分类结果,确定水环境质量等级。
The traditional numerical simulation method and finite element analysis method have the problem of long time for water quality detection.In this paper,the influence of slurry on surrounding water environment in grouting reinforcement of railway engineering is studied by means of comprehensive analysis method.Firstly,the diffusion range of slurry during grouting roadway repair is analyzed to determine the deficiencies in grouting reinforcement process and design a three-step grouting process.On this basis,the environmental quality of the surrounding water was divided into five grades,and the evaluation indexes of single component and multiple components were set.The comprehensive evaluation method was used to scientifically evaluate the water quality of the surrounding water environment,and the evaluation scores of different grades were determined.Then according to the value of each index parameter of the water sample before and after grouting reinforcement of railway engineering,the water environment quality grade is determined according to the classification results of water environment quality.
