Research on navigation clearance of a river-crossing bridge on a special channel in plain river net region

应考虑桥梁路面实际或功能净宽将来的可能变化。

Possible future changes in the physical or functional clear roadway width of the bridge should be considered .

水闸共10孔，总净宽150米，设计过闸流量1020立方/秒。

Water gate altogether are 10 hole , after all horizontal clearance is 150 M , design lockage 's flow-rate is 1020 M3 / sec .

开口改造主要工程之一为在海堤原有码头位置处开口新建一座9孔挡潮闸，每孔净宽24米。

One of the major engineering of the seawall renovation project is to build a 9-hole tidal gates with each hole in 24m width at the original location of the dock .

该船型中剖面设计的难点是既要满足规范对总纵强度的要求，又要增大舱口净宽以提高集装箱装载能力。

This mades it difficult to design its midship section as it shall meet rules ' requirements on longitudinal strength and shall in addition have larger hatchway breadth for larger container carring capacity .

在进行低水头引水枢纽设计时，必然会遇到决定如引水枢纽畅泄冲沙水位、各闸的单宽流量或闸室净宽、各闸底板高程、各闸之间的相对高差等参数问题。

To design a low-head control division project , the question deciding parameters will be met , such as : free flushing water levels , discharge per unit width of gates , net width of gates , elevation of gate sill , relative differences of heights of gates .
