问题 墙体宽度为b、基底宽度为B的刚性条形基础,基础最小高度的计算式是: A. (B-b)/2tana B. [(B-b)/2tana] + 0. 1m C. (B-b)/tana D. [(B-b)/tana] + 0. 1m
选项
答案 A
解析 提示:刚性条形基础仅在基础宽度方向满足台阶允许宽高比要求,其最小高度计算式为(B-b)/2tana。

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.
