软质岩基上一种新型船闸闸首结构的应用

Application of Lock Head Structure of a New Ship Lock on Soft Rock Base

结合北江濛濛枢纽二线船闸,采用BIM技术对传统的分离式、整体式闸首结构,从工程量、止水布置、可靠性及安全性、底板弯矩等方面进行对比分析,针对传统的分离式、整体式闸首结构在软质岩基上存在的弊端,提出了一种新型整体式闸首结构,该结构型式止水布置简单可靠、结构整体性好、工程量较小。

Based on ship lock No.2 at Beijiang Menglin hub, BIM technique is used to compare and analyze the traditional separate and integral lock heads from the aspects of engineering quantities, water-stop layout, reliability, safety and bending moment of baseboard. As for the shortcomings of the separate and integral lock heads built on soft rock base, a new structure of integral lock head is proposed, which has simple and reliable water-stop layout, good structural integrity and small amount of work.
