综合检测技术在岩溶地基注浆质量评定中的应用

山西中南部铁路通道中的一段岩溶地基采用注浆加固处理方法,为了对注浆加固后地基质量进行检测和评价,参考以往的检测与评定方法,通过对各种检测方法的特点进行综合分析总结,采用了注水试验、取芯验证及物探检测等多种手段相结合的联合检测方法,全面反映地基加固质量各个指标,对该段岩溶注浆地基进行检测与质量评定.该综合检测方法的应用,解决了单一检测方法存在的局限性,客观、全面地对岩溶注浆效果和注浆质量进行了综合评价.

On the Application of the Comprehensive Testing Techniques to the Appraisal of the Slip-Casting Quality of Karst Foundation

One section of the karst foundation of the Mid-South Railway Passage of Shanxi Province is consolidated by means of slip-casting. In order to examine and evaluate the quality of the slip-casting-consolidated foundation,a comprehensive analysis and summarization of the characteristics of the various test methods are performed in the light of the past commonly-used test and evaluation methods in the paper, with the combination of various test methods, such as the water-jetting method,the sample test method and the physical exploration method, adopted to reflect all the targets concerning the quality of the foundation in an all-round way so as to test and evaluate the quality of the slip-casting-consolidated karst section of the foundation. The application of the comprehensive test method helps overcome the limitation of any single test method and ensures the objective evalua- tion of the quality of the slip-casting and the slip-casting-consolidated section of the karst foundation in an all-round way.
