摘要
探讨了如何利用概率论与数理统计的知识,以期望损失最小为目标函数,以严格的数学推理来合理地确定最优的试验次数。应用举例说明提出方法的有效性,并就有关问题进行了讨论。
Test is usually made to estimate the geotechnical material parameters. But the test times are not easy to be determined, because many uncertainties are involved in the test. The probability and statistics theory were used to express the least expected loss and to determine the optimal test times through strict mathematic reasoning. A case study was made to show the availability of the presented method, and some relative problems were discussed.
