采用普通克里金法探索优化新增地质勘探点的方法,通过优化勘探位置以尽量少的勘探数量获得最多的地质勘探信息.根据已有的地质勘探点利用普通克里金法对整个勘探区域进行预测,并计算预测值的标准差,将普通克里金标准差最大值所对应的位置设为新增勘探点的位置,以降低预测误差,使新增勘探信息的效用最大化.以澳大利亚国家软土试验中心在100m×100m的软土区得到的26个CPTU试验数据为例,利用提出的新增地质勘探点优化方法探讨了此方法的正确性和精度.
Using common kriging method to explore and optimize the method of adding new geological exploration points, and obtaining the most geological exploration information by optimizing the exploration location with the minimum number of exploration.According to the existing geological exploration points, using the common kriging method, the whole exploration area And calculate the standard deviation of the predicted value, and set the position corresponding to the maximum value of the standard Kriging standard deviation as the position of the newly added exploration point to reduce the prediction error and maximize the utility of the newly-added exploration information.Australia Taking 26 CPTU test data obtained from the National Soft Soil Testing Center in soft soil area of 100m × 100m as an example, the correctness and accuracy of this method are discussed with the proposed new optimization method of geological exploration points.
