Abstract:Based on the construction of the testing section for the lining of J/ping Main Canal in Shandong Province of South-toNorth Water Transfer Project, the main causes of the cracking from the mechanized lining concrete slabs are analyzed from the aspeets of foundation treatment, bedding layer placement, quality of the raw materials for the concrete, placement of the concrete, cutting of the hardened concrete and the curing of the concrete, and then the relevant prevention and control measures are pertinently put forwarcL The practice shows that it is effective to decrease the cracking of the concrete lining slab through the active adoption of those measures.
Keywords:mechanized concrete lining  cracking control measure  South-to-North Water Transfer Project  Jiping Main Canal
