重力坝断面的设计应在保证安全、经济的前提下,满足枢纽布置、运行和施工等各方面要求,故是一个复杂的工作。通常按下列步骤进行。1.简化一些条件,仅考虑作用在坝体上的主要荷载,根据规范要求,使坝体满足下列条件: (1)坝体具有一定的抗滑稳定安全系数,即K≥1.0～1.1; The design of the gravity dam section should meet the requirements of layout, operation and construction of the hub under the premise of ensuring safety and economy. Therefore, it is a complicated task. Usually follow the following steps. 1. Simplify some conditions and consider only the main loads acting on the dam body. According to the requirements of the code, the dam body can meet the following conditions: (1) The dam body has a certain safety factor against sliding, that is, K≥1.0 ~ 1.1;
