permeable pile dike meaning in Chinese
透水椿坝
Examples
- Scouring depth before the permeable pile dike reaches 20 m and the value increase with the upstream angle and flow rate of the coming flow
桩前冲坑最大深度可接近20m ，入流角和流量越大，冲坑越深。 - Three kinds of permeable pile dikes with different seepage rate are tested , and effect of flow control is basically the same with the spur dike ,
试验的三种透水率桩坝，其导流效果与实体丁坝群的基本相同，并未因部分透水及形态不同而使其控导作用明显减弱。 - To improve the river reconstruction technique , it is necessary to investigate mechanism and effect of flow control and aggradation for permeable pile dike
为了探索透水桩坝在黄河治理中的应用前景和应用技术，进一步研究和探讨该工程的透水落淤机理和导流效果，为防洪治河提供理论依据。 - For different upstream conditions , thickness of sediment in the permeable pile dike region may reach 0 . 67 m , and largest thickness is nearly 1 . 9 m , and largest width reaches 1 km
不同入流条件下的主过流区坝段的滩面淤积体厚度可达到0 . 67m以上，最大厚度可接近1 . 9m ，淤积体最大宽度可达1km 。 - In 1960s , it was tested to build permeable pile dike at some places along the lower yellow river . however , some stakes were destroyed by flood due to technique limit then , and efficiency was decreased
在二十世纪六七十年代，透水桩坝工程曾在黄河下游的局部河段做过尝试性实践，由于技术问题，在洪水作用下，不同程度地出现倒桩和断桩现象，其作用和效果受到一定影响。
