问题 某中砂换填垫层的性质参数为天然孔隙比e0=0.7,最大干密度ρdmax=1.8g/cm3,现场检测的控制干密度ρd= 1.7g/cm3,试问该换填垫层的压实系数λc约等于下列( )选项的值。 A. 0.94 B. 0.89 C. 0.85 D. 0. 80
选项
答案 A
解析 根据《建筑地基处理技术规范》(JGJ79—2002)第4. 2. 6条,λc=ρd/ρdmax = 1.7/1.8=0.94。

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
