针对传统水库加固工程混凝土防渗墙可靠性分析受到混凝土防渗墙质量的影响,以提高水库加固工程混凝土防渗墙可靠性分析精度为目的,提出了基于高压旋喷灌浆技术的水库加固工程混凝土防渗墙可靠性分析。根据高压旋喷灌浆技术原理及混凝土防渗墙效果的影响因素,设置合理的高压旋喷灌浆技术施工参数,并根据设置的参数,建立水库加固工程混凝土防渗墙可靠性分析有限元模型,最后通过水库加固工程混凝土防渗墙可靠性分析步骤,实现了水库加固工程混凝土防渗墙的可靠性分析。结果表明,与其他两种可靠性分析方法相比,基于高压旋喷灌浆技术的可靠性分析方法具有更高的可靠性分析精度。

In view of the influence of the quality of the concrete cutoff wall in the traditional reservoir reinforcement project,in order to improve the accuracy of the reliability analysis of the concrete cutoff wall in the reservoir reinforcement project,the reliability analysis of the concrete impervious wall in the reservoir reinforcement project based on the high-pressure jet grouting technology is proposed.According to the technical principle of high-pressure jet grouting and the influence factors of concrete cutoff wall effect,reasonable construction parameters of high-pressure jet grouting technology are set up.According to the parameters,the finite element model of reliability analysis of concrete cutoff wall in reservoir reinforcement project is established.Finally,through the reliability analysis steps of concrete cutoff wall in reservoir reinforcement project,the concrete prevention of reservoir reinforcement project is realized Reliability analysis of seepage wall.The results show that compared with the other two reliability analysis methods,the reliability analysis method based on high pressure jet grouting technology has higher reliability analysis accuracy.
