- Title:
- Approach on the Design of Dividing Method of Water-crossing Section in Intercepting Ditch with Mountainous Flood
- 摘要:
- 详细分析了影响截留泡过水断面的主要因素，提出了采用分段法设计断面的原理及方法。这种新的设计方法，不仅考虑到了暴雨强度和集雨面积，还考虑了过水断面的流量变化和抗冲能力，设计出的断面将沿流向随集雨面积的增加而增大，改变了过去断面首届宽度一致的不合理开挖状况，既保持了我流沟的原有功能，又可使过水断面不冲不淤，还具有开挖量小、占地少的优点。因此，采用分段法设计截流泡过水断面是可行的，有一定实用推广价值。
- Abstract:
- Through analysing the main factors which affect the water-cut of the flood-cut-off ditch,it advances a new theory and method to design the cut by dividing the ditch into several parts. This new method considers not only the strength and area of showers but also the change of the amount of the running water in the ditch and its ability to hold back the flood. Having avoided the improper digging conditions in which the head width and the end width are just the same,the new designed ditch in the direction of the flood will change its size with the changing flood. The ditch not only has the same ability of the old one, but also prevents the ditch-cut frombeing flooded and silted up. Less work of digging and less land-covering are advantages of the new-designed ditch, the water-cut of the new-designed ditch mentioned above is feasible and it is worth popularizing.
