In this paper, the study at home and abroad on the basis of the structure of the steel grid reliability analysis done some exploration, carried out mainly on the following aspects: 1.
本文在国内外有关研究的基础上，对钢网架结构的可靠性分析做了一些探索，主要展开了以下几个方面的工作：1。
Plastic rockery stone stability is mainly rely on the main structure completed, but with the passage of time, steel in the process of contact with air and water, prone to corrosion and rust.
塑石假山的稳定性主要靠主结构来完成，但随着时间的推移，钢材在接触空气及水的过程中，容易发生腐蚀、生锈。
Therefore, the steel is mainly used for low temperature impact of the impact of the components, welding structure and other requirements of higher strength components.
因此，镇静钢材主要用于低温下承受冲击的构件、焊接结构及其他要求强度较高的构件。
