人工环境下无覆盖土壤散湿量计算
Uncovered soil moisture gain calculation in artificial environment
摘要：
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。
Abstract：
Considering the situation of a ruins protection hall with a large floor proportion of uncovered soil in Guangzhou and borrowing some ideas from the calculation method and well-developed empirical formula of groundwater evaporation rate in hydro science, puts forward a method for calculating the uncovered soil moisture gain in artificial environment. In this method, outside evaporation capacity is characterized with the evaporation of exposed water surface and the water supply capacity of soil is characterized with groundwater evaporation coefficient. The design effect of the project indicates that the precision of the calculation method can meet the demand of engineering.
