根据斜坡堤使用工字块体作护面层的情况调查发现,在一些工程中安放双层工字块体的每100米~2实用数量均比规范公式和给定C、P系数计算所得的数量约少8～14％,同时,在模型试放置中通常也难以达到计算所需数量。因此,规范中有关规定和计算公式等宜作进一步的研究和分析,以符合实际安放的情况。本文仅对工字块体护面层厚度和C、P值进行探讨,以供规范修订时参考。
According to the survey of the use of block blocks as protective surfacing for sloped dike, it is found that in some projects, the practical number of double block blocks per 100 m ~ 2 is higher than the standard formula and the given C, P coefficients The number of about 8 ~ 14% less, at the same time, model placement is usually difficult to achieve the required number of calculations. Therefore, the relevant provisions of the specification and calculation formula should be further studied and analyzed in order to meet the actual placement. This article only on the block body protection surface thickness and C, P value for reference when the code revision.
