| Abstract: | During the second Wuhan-Ankang railway construction,the strength behavior of the gray expansive soil and yellow expansive soil in Xiangfan area is studied with some triaxial tests.The test results show that the yellow expansive soil has better water stability than the gray one.The yellow modified expansive soil with 5 percent lime has better strength character than the gray modified expansive soil with 5 percent lime. |
