沥青混凝土心墙的变形特性与施工控制

沥青混凝土心墙的变形是不可避免的，但应力求使心墙变形与坝体变形协调一致。在分析了三峡工程茅坪溪土石坝沥青混凝土心墙的变形特性后，提出了如何通过施工过程的控制使心墙变形与坝体变形相协调，即使在最大剪应变作用下也能发挥其良好的抗渗性能，从而保证工程安全稳定的运行。

Deformation and Control of Asphalt Concrete Core Wall

It may be unavoidable for the deformation of the asphalt concrete core wall, but the deformation of the core wall must be made consistent with that of dam body. Following the analysis of the deformation behavior of the Maopingxi embankment dam with asphalt concrete core, located right side just upstream of the Three Gorges project, the construction measures have been taken to keep the deformation conformity between the dam and core, even in case of the maximum shear strain occurring, with a good impermeability, in order to ensure the safe and reliable operation of the project.
