| 摘 要： | 湖区浸水路基受风浪和水流冲刷双重作用，影响石笼护坡的稳定性。按照水利相关规范，通过对湖区风浪要素等的计算，确定石笼护坡的防护范围和厚度，以确保风浪作用下石笼护坡的稳定，并通过计算近岸的冲刷深度，确定石笼基础的埋深和宽度，使水流冲刷作用下石笼基础保持稳定。此外，当软土较厚时，需进行石笼基础的抗滑移、抗倾覆和地基承载力验算和边坡整体稳定性验算，如抗滑移验算和地基承载力不满足，可采取增大基础宽度或基底下抛填块石方式处理。

Study on Gabion Slope Protection Design for Subgrade in Lake Area under the Action of Wind Waves and Current Scour |
| |
| Abstract: | The sub-water roadbed in lake area is under the double action of wind waves and current scour, and the stability of gabion slope protection was impacted. According to the calculation of wind waves and other factors in line with the codes for water conservancy, the gabion shield and thickness were determined so as to ensure the stability of gabion slope protection under wind waves, moreover, the burial depth and width of gabion base were determined depending on the calculation of near-shore scouring depth in order to ensure the stability of gabion base under current scour. Furthermore, for the gabion base in case of thick soft soil, the stability against sliding and overturning of the base and the bearing capacity of the ground, as well as the global stability of the slope were required to be checked by calculating, and if not satisfied, the base may be widened or filled by riprapping thereunder. |
