膨胀土裂隙问题研究现状及展望
Research Status and Prospect of Expansive Soil Crack Problems
摘要
Abstract
It illustrated the development of expansive soil cracks from the basic characteristics of expansive soils and analyzed the critical role of crack to the expansive soil strength. It summarized the research method and result about expansive soil crack and pointed out we must improve the method of measure and the technique of crack description. It suggested adopting resistivity method,ultrasonic method,CT method,liquid method, calculation method and optical image analysis method to measure the crack,building the mathematical and physical model about the development of expansive soil cracks through mechanics and geotechnical test. The future study included improving the measure method of expansive soil crack,en-suring the quantization index of crack,strengthening the further development of software and applying the research production to actual engineering.关键词
