试验结果表明：在设计荷载下板的强度、刚度、抗裂度及迭合面抗剪性能均能满足规范要求。

The experiment results show that under service loads the slabs 'strength, rigidity, resistance to cracking and sliding are all meet the code requirements.

镍铜，易加工，但抗裂性较差。不受力的灰铸铁加工面及砂眼补焊。

Copper nickel, good machinability bad crack resistance. Repair welding of shole gray cast iron machined surface subject to no load.

用条分法分别确定出抗滑安全系数，安全系数最小的就是最危险滑裂面。

The slip fracture plane with minimum safety coefficient is the most dangerous one .
