问题 边坡勘察,勘探孔深度应穿过潜在滑动面并深人隐定层( )m以内。 A. 1 B. 2~5 C. 6 D. 7
选项
答案 B
解析 根据《岩土程勘察规范》(GB50021 —2001) (2009年版)第4. 7. 4条,勘探线应垂直边坡走向布置,勘探点间距应根据地质条件确定。当遇有软弱夹层或不利结构面时,应适当加密。勘探孔深度应穿过潜在滑动面并深入稳定层2 ~5m。除常规钻探外, 可根据需要,采用探洞、探槽、探井和斜孔。

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.
