块体的回转角、长高比、岩性及负载岩层的高度是影响结构稳定的主要因素。
The major factors that affect the stability of the structure are rotational angle of the voussoir beam, ratio of length and height, rock type and height of carrying rock strata.
在对回转支承进行受力分析、强度校核的基础上，对原设计作了几点改进，如加大钢球直径、增加高度、选用高级合金钢材料等。
Based on the force analysis and strength check on the gyroscopic support, the original design has been improved, such as enlarging the diameter of steel material.
