笔者对“土石坝粘性土的压实”一文提出两点商榷意见。(一)最优含水量与塑限含水量笔者认为,在压实最优含水量与土料的塑限含水量之间,没有明确的关系。最优含水量在特定的条件下是最经济的压实含水量。对于同一种土料,使用不同的压实工具、压实方法和压实功能,以及根据不同的压实要求,最优含水量有不同的数值,而且往往相差较大。表1所列大伙房、清河水库土坝的部分统计资料,便可说明,
The author put forward two points of discussion on the “compaction of cohesive soil in earth-rock dam”. (I) Optimal Moisture Content and Plastic Limit Water Content I believe that there is no clear relationship between the optimal water content for compaction and plastic limit moisture content of soil materials. The optimum moisture content is the most economically compacted moisture content under certain conditions. For the same soil, using different compaction tools, compaction methods and compaction functions, and according to different compaction requirements, the optimal moisture content has different values, and often a large difference. Table 1 shows some of the statistical data of Dahufang and Qinghe Reservoir earth dams.
