【摘要】 以地球物理学基本理论为指导 ,根据地球重力场的特点 ,探讨了水库大坝侧压力及水平静水应力的来源 ,提出了水库大坝水平静水应力产生的主要原因在于水体重力 (即水体地心引力 )的观点。水体重力不仅可以产生竖向静水应力 ,而且还可产生水平静水应力。给出了水体重力所致水平静水应力的科学表达方式 ,提出了水库大坝静水侧压力及水平静水应力计算的一种新方法 ,找出了水库大坝水平静水应力的竖向分布规律(与实际情况基本吻合 )。更多还原

【Abstract】 According to the basic theory of geophysics and characteristics of gravity field of the earth, the author probes into the source of lateral pressure and horizontal static water stress of the dam . On the basis of strict theoretical analysis , that the primary reasons for caused the horizontal static water stress of the dam is the gravity ( that is the terrestrial gravity for the water) has been pointed out in this paper . The water gravity not only can caused the vertical static water stress of the dam , but also it can caused the horizontal static water stress of the dam . It gives the scientific voice way of lateral pressure and horizontal static water stress by gravity of the dam . A new method to calculate the lateral pressure and horizontal static water stress of the dam has been given. The vertical dispersive law of horizontal static water stress of the dam has been discovered ( that tallies completely with reality conditions ) .更多还原
