The practices showed that the suspension arch method of drifting is an effective way of drifting in unstable strata.
实践证明，悬拱法是不稳定岩层中平巷掘进的有效施工方法。
Based on the theory of rock mechanics and the principle of drifting, the author proposed the suspension arch method of drifting in unstable strata.
本文在总结先拱后墙平巷掘进经验的基础上，根据岩石力学理论和平巷掘进原理，提出了平巷掘进的悬拱法。
Arch is the opposite effect on the suspension bridge, suspension bridge cables in the freedom of those who provide support force where it is from the bridge pillars at both ends of its fixed upward.
拱桥则是相反于悬索桥的作用，在那些悬索桥缆绳自由的提供支撑力的地方，拱桥却是从它的两端支柱固定的向上弯曲。
The whole structure was the suspension system before the completely shut of arch rib. The safety control is very important.
但在拱肋完全合拢之前，整体结构是一个悬吊体系，其安全控制相当重要。
There are four categories of basic structure can be used as water or obstructions on the bridge: rigid frame bridge, cantilever bridge, arch, and suspension system.
这里有4类基本结构可以用作水面上的或障碍物上的桥：刚架桥、悬臂桥、拱桥、和悬索桥体系。
Out-laid anchor heads are used for suspension Bridges mostly because they have the advantages such as attractive in appearance, not weakening arch and girder structure connected, and easy to install.
外置式锚头多用于悬索桥，具有造型美观，不削弱被连接的拱、梁结构，施工安装方便等优点。
Combining the construction practice, the article introduces the construction method of arch box suspension hanging.
结合工程实例，介绍拱箱悬索吊装施工方法。
