1981年8月21日嘉陵江发生了一次特大洪水,宝成线宝略段的铁路河岸冲刷防护工程被冲毁甚多。当时我院担任该段水害的修复工程设计。为加快设计的进展,我们编制了《铁路路基冲刷防护基础》参考图,其中编入了较常采用的防护型式:浆砌片石护坡配以脚墙基础,如图1。 On August 21, 1981, an extraordinary flood occurred in the Jialing River. The erosion of the river bank erosion protection project at Baolu Line of Baocheng Line was largely destroyed. At that time, our hospital served as the water damage repair engineering design. In order to speed up the design progress, we have compiled a reference map of “Foundation for Railway Roadbed Scouring Protection”, which incorporates the more commonly used types of protection: mortar and stone slope protection with footwall foundation (Figure 1).
