重力坝建基面选择的研究

Study on Selection of Foundation Base of Gravity Dam

介绍了一种如何合理选择建基面的方法 ,即在对坝基岩体弱风化带进行细分的基础上 ,拟定数个建基面高程 ,然后验证渗流条件、抗压强度条件、变形条件和抗滑稳定条件 ,确定最优建基面。并给出某重力坝工程的应用实例。

A method for rationally selecting the foundation base of gravity dam is described. Firstly, dividing the weak-weathered base rock into several zones and drawing up several relevant base level schemes; then, verifying the physical-mechanical properties(seepage rate, compression strength, deformation, stability against sliding) of every zone; at last, selecting optimum base level by comparing these schemes. An example is given to illustrate this method.
