测量了橡胶坝材料刚性环和柔性环在不同水平约束应力条件下的垂直和水平设置膨胀。刚性环的垂直膨胀显著大于水平膨胀，而柔性环的差异不显著。建议使用很少或没有限制水平膨胀的柔性环来减少模具变形。
Vertical and horizontal setting expansion was measured under different conditions of horizontal restrictive stress provided by a rigid ring with liners and a flexible ring of rubber dam material. Vertical expansion was significantly greater than horizontal expansion in the rigid ring and not significantly different in the flexible ring. The use of a flexible ring offering little or no restriction to horizontal expansion is recommended to reduce mould distortion.
