石灰土基层施工,一般凭经验选用土壤及其不同的土壤塑性指数而采用不同的含灰剂量,在冲积平原地带,粉性土壤和低塑指土占绝大多数,过去由于对土的指数要求较高,找寻土场困难,甚至造成远距离运土情况,1975年我们在沙(市)洪(湖)线9～17公里石灰土基层试验路段中,对于不同塑性指数的粉性土壤及其几种不同的含灰量,在工地作了抗压试验,在自制的工地轻便压力机试压近20个试件中,风干试件抗压一般在10公斤/厘米~2以上,最高达到24公斤/
The basic construction of limestone soil generally adopts different levels of soil ash content and soil plasticity index, and uses different ash content in alluvial plain area, and the soil and plastic soil account for the overwhelming majority. In the past, due to the requirement of soil index High, to find the soil field difficulties, and even caused by long-distance soil transport in 1975, we in the sand (city) Hong (Lake) line 9 ~ 17 km of limestone grassroots section, for different plasticity of the soil and its plastic Several different ash content, made a compression test at the site, in the home-made portable press pressure test nearly 20 specimens, air-dried specimen compression is generally 10 kg / cm ~ 2 or more, up to 24 kg/
