一段古建筑的专业文字求翻译成英语

Question

藏族碉房的密檩结构皆为平铺直放，构件间仅有少量的插榫，大部分构件无连接措施，是比较原始的构造方法。至于结构稳定性是靠厚重的屋盖荷载（一般屋盖覆土厚度达30cm）的重压，以保持垂直的稳定；而厚实的石砌外墙又限制了构架的水平位移，使构件稳固不倒。羌族民居构架方式与藏居相同，亦为全木构架式与墙承重的混合构架式。
元江、红河、绿春、元阳一带盛行土掌房，亦是平檩式构架。柱距约3m左右，平梁截面约10cm乘20cm，若跨距稍大，则在梁下另加随梁枋，木圆榫直径约10cm，檩距30cm，土铺竹片、荆条、柴草，顶部覆盖20cm厚黏土。围护外墙为夯土墙或土坯墙。若是利用外墙作承重墙，则需要在墙顶上铺设卧梁，将梁檩搭于其上，以分散压力。因红河地区夏季炎热，故外墙墙顶与屋盖之间留有空隙，以解决室内通风要求。同时为保护土外墙，平屋盖四周皆有出檐，其外观与羌族民居有很大不同。

The purlin structure of Tibetan bleaching room are flat out straight, only a small amount of insert tenon between components, connectionless measures, most of the components is the structure of the original method.As for the structure stability is to rely on the roof of heavy load (general roof covering 30 cm in thickness), the weight of to maintain the stability of vertical;The thick stone walls and limit the horizontal displacement of the architecture, the component is not stable.Qiang folk house architecture style and hidden in the same, and also for all the wooden frame and wall frame of hybrid bearing type.
Including yuanjiang, honghe, green spring, yuan thing with popular, the house also is flat purlin truss.Column from about 3 m or so, about 10 cm x 20 cm, flat beam section if span larger, is under the beam plus with liang fang, the round wood tenon about 10 cm in diameter, purlin is apart from 30 cm, soil spread of bamboo, thorns, straw, the top cover 20 cm thick clay.Retaining wall of rammed earth wall or adobe wall.If outer wall is used as the main wall, need to lay lie on top of the wall beam, beam purlin will build on it, to spread the pressure.Because the honghe region hot summer leave gaps between exterior wall and roof, in order to solve indoor ventilation requirements.Around the exterior wall to protect the soil at the same time, the flat roof is out of the eaves, its appearance and qiang folk houses are quite different.
