南水北调中线工程改性土削坡余料的利用南水北调中线工程改性土削坡余料的利用 摘要:南水北调中线工程为解决部分标段因膨胀土渠道开挖保护回填缺少合适土料,进而采纳水泥改性土换填施工;为保证换填面碾压密实度和机械安全作业宽度,渠坡每层换填需要有一定的超填宽度
在渠坡衬砌施工前,需将坡面削至设计边线,因此就造成了改性土削坡预料的产生
如不解决好削坡余料的利用,将会造成大量资源和资金的浪费

To get enough compact density and safety working surface, each filling layer should have extra width outside of design line
Before the lining on slope, we should cut off the extra slope to design part, the residual material will be producted in this progress
If the residual material w
