高速公路采空区治理的综合检测优化评价

The Compositive Detection Optimization Assessment of the Treatment Project Using Grouting in the Mined Out Area Beneath the Highway

目前国内外有许多采空区治理效果检测方法,但尚没有成熟可靠的技术方法,在公路采空区治理监测检测中无现行规范、规程和标准可遵循。根据国内典型公路下伏采空区治理设计与监测检测试验研究,系统确立采空区治理效果检测体系与质量指标,明确采空区治理检测的原则、方法与综合检测优化程序;并研究讨论采空区治理效果检测数值模拟定量计算,为进一步研究采空区治理效果监测检测技术明确了方向。

A number of methods have been used to evaluate results derived from the treatment project in mined out area though most of them is not certain with accurate and confirmed results at present. And there were no reliable code or regulation as well any criteria to follow in highway construction. In the paper, based on surveillances and instruments to evaluate the results of the treatment project using grouting in the typical mined out area beneath the highway in China, a system to evaluate results of the treatment is discussed and some criteria are proposed. Principle, methods and synthetic procedure for trying to test results of the treatment project in a mined out area were confirmed. Also, a results derived from the numerical analogy are discussed as a methods to evaluate results of the treatment project in the mined out area. It shows a picture for the further researches to evaluate results of the treatment project in the mined out area in future.
