地面沉降是世界各国许多城市面临的地质灾害之一，故沉降量的预测十分重要.根据地下水动力学原理，借鉴释水系数的定义，提出了“长期释水系数”的概念以得到一种预测地面沉降量的简单算法.为检查这种方法的可靠性，利用天津市截止到1993年的地下水水位资料及其它有关水文地质资料，对天津市区到1993年累计产生的地面沉降量进行了计算预测计算结果与实测结果比较表明，愈靠近沉降中心，计算结果的可靠性愈好，远离沉降中心处会产生一定误差，但总体趋势是正确的，说明计算方法可行.

Ground subsidence is one of the primary geological hazards in many cities of the world, so the pre-diction of subsidence amount is always a central issue. Based on the theory of ground water dynamics, theauthors put forward the conception of long-term discharge coefficient and the calculation method of it accord-ing to the definition of discharge coefficient to simplify the calculation of subsidence amount. The subsidenceamount of Tianjin City to the end of 1993 was calculated and predicted using the method. The result showsthat the nearer to the subsidence center, the better the reliability of the calculation, and some error may existfor the points far from the center but the general tendency is correct, indicating the method is feasible.
