Abstract

The regulation of earth resistivity and elastic wave velocity with the change of compaction degree under different moisture contents is studied by experiment. In addition, regression analysis is conducted on the relationship between compaction degree and soil resistivity and elastic wave velocity. Based on this quantitative research, the method for joint evaluation of soil compaction degree with electrical resistivity and elastic wave velocity is proposed. This method breaks the narrow application range in which it is only suitable for one kind or category of soil. With electrical resistivity in joint evaluation method, survey line can be arranged in a large scale; the design requirement on compaction degree and its evenness in the whole area can be evaluated; the dissatisfaction about compaction degree in the area can be obtained. All of these cannot be realized by other methods. Therefore, this work takes this method as the general survey method in common area. With elastic wave velocity in joint evaluation method, compaction degree at specific spot can be surveyed as by traditional methods; compaction degree in specific depth can be measured. Therefore, this work takes this method as the method for secondary evaluation or evaluation of specific area after evaluation by spot test and resistivity method. Moreover, two methods in joint evaluation method can be verified by each other to ensure the correctness of measurement and make effective evaluation for soil compaction degree.
