中文摘要：

采用现场实测和借鉴水土流失统计方法,揭示了夯土风雨侵蚀损耗机理和规律,进而提出夯土风雨侵蚀损耗计量公式;并结合土楼当地风、雨气象数据,计算出近年来夯土的年侵蚀量.采用缩尺土楼模型,进行抗压试验,研究土楼结构性能; 进而分析夯土墙风雨侵蚀后满足承载要求的临界墙厚,从而可预测夯土墙使用寿命,为福建土楼科学保护提供依据.

英文摘要：

Through statistical methods and field test about soil and water loss, the mechanism and rule of rammed earth wind and rain erosion were revealed, the measurement formula of wind and rain erosion loss were built. And then, through the local wind and rain of meteorological data, the rammed earth annual erosion in recent years was calculated. At last, based on the earth building’s minimize model compressive test, the earth building’s properties were studied, the rammed earth wall’s critical depth to resist loads were analyzed, the rammed earth walFs surplus life were predicted. The results could provide adaptive scientific basis for Fujian earth building pro-tection.
