问题 土石坝采用进退错距法施工,若施工工作面宽3.0m,碾压机械碾滚净宽1.5m,设计碾压遍数为5遍,则错距碾压宽度为( )m。
选项 A. 0.3 B. 0.5 C. 0.6 D. 2.0
答案 A
解析 错距碾压宽度b (m)按下式计算:b = B/n,式中B为碾滚净宽(m); n为设计碾压遍数。故 b=1. 5/5 = 3。

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).
