Other Abstract



Three new-style prevention and control structures were proposed based on characteristics of Laohuzui large-scale collapse: tetrahedron for underwater slope protection, pile-underpinning-wall structure and pile-underpinning-foundation structure. Their main construction details were expounded. The study showed that by calculation and analysis the anti-erosion properties was related to it’s representative size, friction angle, relative density, the average flow velocity of river and bank slope angle. And some time, The formula that reflected the relation between the length of tetrahedron and other above-mentioned parameters was deduced. Comparing other structure by rigid coupling between pile and wall, pile-underpinning-wall structure by hinge received less shearing force and bending moment on even ground. Accompanying pile markedly enhanced integral bending stiffness in pile-underpinning-foundation structure and the integral bending stiffness increased nonlinearly with accompanying pile ratio.
