Abstract: A new technology of constructing ultra-thin antiseepage walls by polymer injection has been developing. The mechanism of polymer expanding and filling the slot formed by the direct pushing method is studied in this paper. ...

Abstract: In order to overcome the disadvantages of high computational complexity and inconvenience when forecasting deformations of surrounding rock by using support vector machine of standard form (Vapnik SVM), a new deformation ...

Abstract: In view of trust region algorithm has good global convergence for solving non-linear quadratic programming problem, the effective elastic module’s damage factor and the damage distributed function was introduced by FEM ...

Abstract: Polyurethane has been widely used as new chemical grouting material. Expansion characteristics caused by chemical reactions make polymer grout different from other types of grout. To throw light on the diffusion process ...

Abstract: The polymer antiseepage wall is a new technology for the reinforcement of earth dams. It has the advantages of being efficient, ultrathin, minimally invasive, and economical, which makes it even more popular and widespread ...
