在喷射急流下,泄水口下游端金字塔型消力墩上的力取决于许多因素、例如流速和墩高等等.这里将介绍一些经验成果.众所周知,消力槛和消力墩通常都是用以稳定水跃并消散各种水工结构例如溢洪道、水闸、泄水底孔、或跌水下游的剩余动能.通常将此种水跃,称为强迫水跃.和传统的自由水跃的特性大为不同.强迫水跃的特性在于不仅是分离水流和形成墩后涡流,而且在消力墩上
Under jet stream, the force on the pyramid-shaped piers downstream of the spout depends on many factors such as flow rate and pier height, etc. Here are some of the empirical results: It is commonly known that both siping and piers are commonly used Stabilize the jets and dissipate the residual kinetic energy of a variety of hydraulic structures such as spillways, flood gates, scuppers, or downstreams. This type of jerk is often referred to as forced jerk. Different. The characteristic of forced water jump is not only to separate the water flow and form the post-pier eddy, but also to exert pressure on the pier
