| 摘 要： | 现行JTJ 307—2001《船闸水工建筑物设计规范》对底板自重在内力计算中的考虑没有明确规定,不同设计者根据具体地基条件进行不同程度折减。通过以往工程建设经验及数值分析,建议宜借鉴和参考SL 265—2001《水闸设计规范》,即可不考虑底板自重,折减程度可为100%,同时建议船闸设计规范中补充类似条文和说明,并对此作进一步的验证。 |

| Abstract: | Current Code for Design of Hydraulic Structure of Shiplocks(JTJ 307—2001) provides no definite regulations considering the floor’s deadweight in the internal force calculation,and various reductions have been made by different designers according to the detailed foundation conditions.Based on construction experiences and calculation analysis,Design Specification for Sluice(SL 265—2001),which indicates the floor’s deadweight is not to be considered and the reduction degree is 100%,is suggested to be utilized as the design guide and reference.And it is recommended that similar clauses and directions should be supplemented in the Code for Design of Hydraulic Structure of Shiplocks(JTJ 307—2001). |
| Keywords: | hydraulic structure elastic foundation beam method self-weight of bottom floor shiplock |
