问题 当基坑开挖较深,降水深度>6m且场地狭窄时,可采用( )法降水。 A.明排水 B.电渗井点 C.轻型井点 D.喷射井点
选项
答案 D
解析 明排水法的降水深度小于2m,狭窄的场地不适于布置轻型井点,而电渗井点适于透水性差持水性强的淤泥和淤泥质土;当基坑开挖较深,降水深度>6m且场地狭窄时,可采用喷射井点法降水。

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.
