摘要
通过对设垫层坝内埋管结构的计算分析，论证了在钢管外周设置垫层可以有效降低钢管外围混凝土的拉应力，提高混凝土抗裂安全。
Based on the analyses of the penstock embedded in the dam with cushion layer,this paper has verified that placing cushion layer between penstock and concrete can reduce tension stress and improve the anti cracking safety of surrounding concrete,and thoroughly bring penstock into full play.
