查询词典 piers

A finite element numerical model for arch dam-gravity pier-foundation system was established to evaluate the effect of high gravity piers on the stress, deformation and anti-sliding stability of Sizhai arch dam, taking the following factors into account, such as the possible elastoplastic deformation of foundation rocks and the nonlinear interaction between the interfaces of gravity pier-dam foundation, the joint surfaces beneath the right bank, and the interfaces of arch dam-gravity pier.

摘要为评价高重力墩对四寨拱坝的应力变形和抗滑安全的影响，建立了拱坝－重力墩－地基系统的有限元数值模型，其中考虑重力墩－基础、右岸夹层和拱坝－重力墩等交界面的非线性相互作用，以及基岩材料的弹塑性变形行为。

In order to study local scouring field near the pier with sediment control dam, the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek. This paper analyses the velocity distribution in the scouring pool of pier and takes turbulent strength distribution in different direction. Three new characters for the local scours of piers with the sediment control dam are analyzed and the dam's applicability is brought forward.
