Spatial random fields-based Bayesian method for calibrating geotechnical parameters with ground surface settlements induced by shield tunneling

Acta Geotechnica - The precise mechanics simulation of shallow shield tunneling through soft soil is an engineering challenge. Elastic–plastic deformation causes progressive failure for the...     

阳江-电白滨海稀土砂矿地质特征和找矿前景

阳江－电电滨海稀土砂矿床,是富含独居石、磷钇矿等副矿物的变质岩和混合岩经长期风化和地表水搬运等地质作用,副矿物在滨海地带富集而形成的矿床,主要赋存于沙堤和古河口扇等地貌单元中;在沿岸１００ｋｍ范围内已证实有大、中、小型矿床（点）１０多处,南山海矿床规模大、品位高、易于开采,可作为这类矿床的代表。通过高分辨率单道地震、旁侧声纳、测深、声纳浮标和钻探等手段的调查验证,阳江－电白滨海区含矿砂层发育,含矿
