【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。更多还原

【Abstract】 On basis of the theory of geophysics and characteristics of gravity field, the authors probe into the source of lateral pressure and horizontal static water stress of the dam. A strict theoretical analysis proves that the primary cause of the horizontal static water stress of the dam is the gravity (the terrestrial gravity of the water). It is discovered that the gravity can not only cause the vertical static water stress of the dam, but also the horizontal static water stress as well. Hence, the gravity reveals the lateral pressure and horizontal static water stress. And this paper intends to argue for a new method to calculate the lateral pressure and horizontal static water stress. This leads to the assumed discovery of the vertical dispersion in contrast to the horizontal static water stress of the dam.更多还原
