【摘要】 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.更多还原

【Abstract】 The method of optimizing new geological exploration will be explored using ordinary Kriging method to determine its optimal locations.According to existing site investigation,the parameters of interests are predicted using ordinary Kriging method over the whole site first.Then the standard deviations of the predicted values are evaluated to facilite the following optimization.Locations of the new site investigation are selected as the locations with maximum ordinary Kriging standard deviation in order to reduce the predicted error and maximize the value of new investigation.Finally,an example with 26cone-penetration test undrained(CPTU)is performed to demonstrate the optimization method.These tests were performed by the National Soft Soil Field Testing Facility of Australia in an area of 100m×100m;the rationality and the accuracy of the method are discussed.更多还原
