Abstract
Quantile Value Method based on quantile is to be discussed in this paper. First, verifying the QVM. A simple case is just including two randam variables which used to verify the QVM. The QVM will transplant design location to the validation case while design point used in the design value method (DVM). The QVM validation results will be compared with the DVM results in the standard Gaussian space. They showed that assume constant partial factors cannot achieve uniform reliability levels for scenarios with non-constant COVs.
Second, there are three more complicated and realistic geotechnical design examples will be studied. The main conclusions in the simple case still hold in these realistic cases. In addition, we observed some interesting results in these realistic cases.
Linking site investigation efforts to final design savings with simplified reliability-based is investigating in the last. There are four simple reliability-based design code used to calibrate partial factors under virtual site investigation information. The virtual site survey information is divided into 20 groups based on accuracy and the number of test. According to different calibration methods there are one or twenty partial factors/quantiles will be transplant into validaton pad foundation case. The results showed the the QVM can effectively link site investigation efforts to final design davings.
