摘要
在现有的剩余推力法中,没有对地下水位动态变化的条件下的渗透压力做出明确的说明,因此在对斜坡稳定性评价和设计中难以客观的给出。针对这一状况,在已有研究基础上,提出了将地下水位对库水位的响应应用到剩余推力法中,进一步明确了当库水位波动时对斜坡岩土体产生的渗透压力,然后把这些量化关系应用到剩余推力法公式和程序中,最后通过一个实例分析,计算表明更符合实际设计要求。
<Abstrcat>It is hard to obtain the objective infiltrating force in assessment of slop stability by existing remained slip force method as the remained slip force method dose not specify the infiltrating force under the condition of underground water lever fluctuating. The underground water lever response to reservoir water lever was proposed to apply to the remained slip force method. The infiltrating force over slope was further determined, and the quantitative relations were added to formulas and programs. The study showed that the improved method adapted well to the design requirements.
