摘要
为解决某土石坝坝体内混凝土防渗墙连续性较差问题,提出了两种防渗加固方案,综合考虑工程安全性、加固彻底性、防渗质量可靠性等多方面因素,采用了新建混凝土防渗墙方案2;考虑渗流体力因素模拟计算推荐方案加固后新建混凝土防渗墙的土石坝应力、变形分析。结果表明,两种工况条件下,加固后混凝土新、旧防渗墙的压、拉应力值均在混凝土强度允许范围内,病险除控效果较好。
To solve the problem of poor continuity of concrete cut-off wall in an earth-rock dam. Two kinds of anti-seepage reinforcement schemes are put forward. Considering the safety, thoroughness and reliability of the project, the scheme 2 of the new concrete anti-seepage wall is adopted, and the stress and deformation analysis of the earth-rock dam with the new concrete anti-seepage wall after the proposed scheme is consolidated is simulated by considering the seepage force factor. The results show that the compressive and tensile stresses of the new and old impervious walls are within the allowable range of concrete strength under the two working conditions, and the dam disease control effect is good.
