针对广州某遗址保护大厅内多为裸露土壤的情况,借鉴水利科学中潜水蒸发量的计算方法及成熟的相关经验公式,提出了人工环境下无覆盖土壤散湿量的计算方法。在该计算方法中,用暴露水面的蒸发量来表征外界蒸发能力,用潜水蒸发系数来表征土壤的输水能力。设计效果表明,该方法的计算精度能满足工程实际的需要。
Aiming at the situation of exposed soil in the protection hall of a ruin in Guangzhou, the calculation method of unspoken soil moisture loss in artificial environment is put forward according to the calculation method of submersible evaporation in water science and the mature empirical formula. In this calculation method, the evaporation capacity of the exposed water surface is used to characterize the external evaporation capacity and the evaporation coefficient of the water surface is used to characterize the water transmission capacity of the soil. The design results show that the calculation accuracy of the method can meet the actual needs of the project.
