土壤剪切波速与标贯击数关系的统计分析
|
摘要
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。
This paper analyzes the relationship between shear wave velocity of soil and standard penetration test blow count including fine sand,medium sand,rough sand,gravelly sand,silty clay,clay,and then provides empirical formula and suitable depth.The paper also does a multivariant statistical analysis among shear wave velocity,depth of soils and standard penetration test blow count for fine sand,medium sand,rough sand,silty clay with two methods:Method 1 and Method 2.The results show that:it is necessary to subdivide soil type further before giving the regressive relation between shear wave velocity and standard penetration test blow count;for gravelly sand,it is advisable to get shear wave velocity and standard penetration test blow count by field measurement;Method 1 and Method 2 both could obtain satisfactory results,while Method 1 is slightly better than Method 2.
