摘要
深厚覆盖的第四系冲洪积砂卵砾层堤岸,在大流量的洪水冲刷和淘蚀作用下易产生坍塌、跨塌,甚至导致滑坡的产生,是由于其二元结构岩性特性,上松下紧导致其抗冲刷、抗淘蚀能力较差,针对此类堤岸采用何种类型护坡形式是值得研究和探讨的课题,而高压旋喷灌浆+浆砌石挡墙护岸型式在施工过程具有占地少、施工难度低、施工工期短,护岸建筑物具有抗淘刷、抗剥蚀作用强的特点,其技术上是可行的,是一种有效的防洪堤治理方案之一。
The embankment bank of quaternary alluvial-proluvial sand-gravel layer with deep cover is liable to collapse,collapse and even landslide under the action of large flow of flood scouring and erosion.Due to the loosening and tightening of lithological characteristics of binary structure,it has poor scouring and erosion resistance.The type of slope protection used by such embankment is a subject worthy of study and discussion.The scheme of high-pressure rotary grouting combined with grouting and masonry retaining wall bank protection has the characteristics of small land occupation,low construction difficulty and short construction period,and the antiscouring and anti-denudation of bank protection structures are also strong.It is technically feasible and is one of the effective flood protection embankment treatment schemes worth promoting.
