The relationship between elastic strain energy and the reduction coefficient can be used as criteria in slope stability analysis using strength reduction method.

研究结果表明：采用强度折减法，当边坡处于稳定状态时，折减系数增大引起边坡变形增大，导致边坡体弹性应变能随之增大；但是，边坡岩土体能够承受的弹性应变能是有极限的，当折减系数增大到某一值时，边坡体的弹性应变能达到极限，再增大折减系数将导致边坡失稳破坏；边坡体弹性应变能与折减系数服从指数关系；利用弹性应变能与折减系数关系曲线得到的边坡安全系数与采用其他经典的方法所得边坡安全系数基本一致，弹性应变能随折减系数变化而变化的规律可以作为边坡稳定性强度折减法分析的失稳判据。

The research result shows that the flowability, moldability, cohesiveness of high performance concrete of hill sand are significant by comparison with ordinary concrete on mechanical properties, long term properties, and durability. Motar flowability decreases with the increase of single-mixed active additive. The flowability can be largely improved by double mixing of active additive and super plasticizer NF. This is because not only the active additive has filling effect but also the dispersing effect induced by surface action between additive and super plasticizer NF. And the optimal content of materials are: super plasticizer NF≥0.8%, fly ash 20%, PS 20~30%,zeolite powder≤20%,SF 5~8%; The negative influence of hill sand powder should be avoided by controlling of powder content and the use of active additive and super

研究表明：随着单掺活性掺合料掺量的增加，砂浆流动性减小，活性掺合料与萘系高效减水剂NF双掺使用，比使用同样剂量萘系高效减水剂NF的基准浆体流动性明显增大，这是由于玻璃体材质活性掺合料不仅有填充效应，更主要的是它与高效减水剂之间的表面物化作用产生了分散性，而活性掺合料对浆体的流化作用效果主要是依赖于其分散性；能有效改善胶砂流动性的适宜掺量为：萘系高效减水剂不小于0.8%，粉煤灰掺量为20%，PS掺量为20~30%，沸石矿粉掺量不宜大于20%，SF掺量为5~8%；通过对粉末含量的限制，并借助活性掺合料、高效减水剂的合理使用，就可以避免山砂粉末含量的负面影响，配制出密实度高，抗渗性能优异，具有良好的耐久性能，并具有良好的体积稳定性的山砂高性能混凝土。
