| Abstract: | This articale discuss the basic features of relaxed crack in the area of dam site, infurther, study the characteristics of engineering geology, The growth of relaxed crack cause thechange of the engineering geology Characteristics of rock mass and influence the stability analysisof dam foundation, the depth of foundation excavating. So it's essential to study and find the mea-sures to ensure the stability and sefty of dam, reduce its cost and period of construction. |
