混合式坞墙(闸墙)是建于风化岩地基上的船坞坞墙(船闸闸墙)结构型式之一。其断面型式如图1所示,上部为形似L的挡土墙,下部为厚衬砌墙。该结构较重力式坞墙可减少大量土石方开挖和回填工程,从而降低了造价,因此愈来愈引起船坞(船闸)设计和建造者的关注。 The mixed dock wall (brake wall) is one of the structures of the dock dock wall (the lock gate wall) built on the weathered rock foundation. The section pattern is shown in Fig. 1. The upper part is a retaining wall shaped like L and the lower part is a thick lining wall. Compared with the gravity type docking wall, this structure can reduce a large amount of earthwork excavation and backfilling works, thereby lowering the cost. As a result, more and more attention has been paid to the design of the dock (lock) and the builders.
