| 摘 要： | 脉动上举力是导致消力池或水垫塘底板发生揭底破坏的主要原因之一.在设计溢洪道衬砌板块的厚度时必须考虑脉动压力的作用.该文对脉动上举力的形成进行了理论分析和推导.得出板块所承受的瞬时最大脉动上举力的表达式.并据此给出衬砌板块的设计厚度公式,通过与实验结果等的比较,认为这一结果是合理的.

| Abstract: | Fluctuating uplift force within rock or block cracks is one of the main causes of spillway damage.The effect of fluctuating pressure must be concerned in the design of thickness of lining slabs.In this paper,the generation of fluctuating uplift is studied by theoretical analysis and deduction.The endurable transient maximum fluctuating uplift for slabs is expressed.Based on this,the design thickness expression of slabs is deduced.Through comparing with the experimental result,it is validate that this inequa... |
