Advances in Research on Construction Disturbance to Soil and Related Testing Techniques

YE Wei-min,LI Qiu-fang,CHEN Bao,HUANG Yu,MEI Zheng-jun(1.Key Laboratory of Geotechnical and Underground Engineering of Ministry of Education,Tongji University,Shanghai 200092,China;2.United Research Center for Urban Environment andSustainable Development,the Ministry of Education,China,Shanghai 200092,China)  
Recently,the common indexes employed for evaluating soil disturbance during underground construction include pore water pressure,undrained modulus,pore ratio,stress path,strain,various moduli,and so forth.According to these indexes or their combinations,all the evaluating methods commonly used can be classified into single-factor or multi-factor evaluation techniques.However,the in-situ testing technologies,such as CPT,BOTDR and TDR,are highly accurate and reliable.With the increasing environmental protection requirements to the construction disturbance,studies of construction disturbance evaluation index system for evaluating slight construction disturbance,as well as the combination of in-situ tests and lab tests for the more accuracy and quantitative evaluation techniques for the test of slight construction disturbance to soil,are important work to be carried out in the future.
