摘要
针对临朐县砂质山区梯田建设中存在的埂坎过陡或过缓问题,经剪切试验对埂坎的稳定性进行分析表明,采用砾质细砂土筑埂时坡角可取37°,细砂土筑埂时坡角可取34°。经试验设计的一种复式坎坡,与传统的直线坎坡比较,埂坎占地减少40%~43%。
Aimed at the issues of
too gentle or too steep edges in terrace building in sandy mountains of Linqu county, shear tests
have been taken to study the terrace edge stability and the results show that 37 and 34 slope
angles should be adopted respectively to gravelly fine sandy loam and fine sandy loam. A
compound slope terrace edge is designed after experiment which decrease the land occupation by
40% to 43% comparing to traditional direct slope terrace edge.
