原位地基浸水试验中蒸发量的测定方法及计算

Evaporation Mensuration and Calculation in Immersion Test of In Situ Foundation

为了获得高精度地基原位浸水试验现场的水面蒸发量,一般采用现场器测法并经地区蒸发器修正系数修正后确定。在缺乏实测资料情况下,可采用经验公式或根据热量平衡原理来计算试验场地水面蒸发量。如果对蒸发量要求不高或者蒸发量与浸水量之比特别小,也可采用现场简易测量法来测定试验场地水面蒸发量。

In order to obtain a highly accurate evaporation in the immersion test of the in situ foundation, in situ mensuration is normally used and then the measurement corrected with the correction coefficient of the area evaporator. In case information of actual measurements is lacking, the evaporation of the site under testing can be calculated using the empirical formula listed in this paper and the principle of thermal balance. And, simple and easy in situ mensuration can be used to determine the evaporation of the site under testing if evapo- ration is not so crucial or the ratio of evaporation and immersion is especially small.
