According to the geological condition and measured geostress data of the utralong-distance water diversion project. a 3D inversion calculation model of the initial geostress field of the water diversion route was established. The initial geostress field of the water diversion route was exactly simulated through the method of generalized regression neural network (GRNN) optimized by ge... https://darthomes.shop/product-category/bird-feeders/
