统计分析了细砂、中砂、粗砂、砾砂、粉质粘土和粘土的土壤剪切波速与标贯击数的关系,给出了相应的经验公式及适用埋深;采用方法 1和方法 2两种方法对细砂,中砂,粗砂,粉质粘土对土壤剪切波速与埋深及标贯击数进行了多元统计分析。结果表明:有必要将土类进行细分,再给出剪切波速与其标贯击数的回归关系;砾砂宜采用现场测试其剪切波速与标贯击数;两种方式都得到了较令人满意的结果,采用方法 1比方法 2略优。
The relationship between the shear wave velocity of soil and the number of standard penetrations of fine sand, medium sand, coarse sand, gravelly sand, silty clay and clay was statistically analyzed. The corresponding empirical formula and the applicable burial depth were given. Multivariate statistical analysis was made on the shear wave velocity and depth of soil shear and the number of standard penetrations of fine sand, medium sand, coarse sand and silty clay by using two methods. The results show that it is necessary to subdivide the soil class and then give the regression relationship between the shear wave velocity and its standard penetration number. The gravel sand should be tested on site with the shear wave velocity and the number of standard penetration. Both methods have been compared Satisfactory results, using Method 1 slightly better than Method 2.
