The results show that the optimal inspection instants should take place before the reliability index reaches the minimum acceptable reliability index. 結果表明，最優(yōu)的檢測是在結構的可靠指標低于最低可靠指標前就對結構進(jìn)行檢測。
By contrast, the paper calculated the reliability index of the abutment after changing variable quotiety of the stochastic variable. 作為對比，本文還在改變各隨機變量變異系數的前提下，計算了壩肩巖體各高程的可靠指標。
