摘 要：为分析采用强度折减法确定边坡安全系数过程中边坡弹性应变能随折减系数变化与边坡失稳破坏的内在联系，建立数值模型，记录边坡弹性应变能与折减系数关系曲线；通过对某边坡的分析，绘制弹性应变能与折减系数关系曲线。

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 relationship between the ratio of Ca to Si with shrinkage value was needed to be studied further.The strength of M-AAS was comparatively high, but the flexural strength was regressed in the long term. The compressive and flexural strengthes of 3 days were able to surpass 8MPa and 78MPa, respectively, and compressive strength of 90 days were all around 100MPa, but compared to flexural strength of 28 days, the flexural strength of 90 days was regressed by 19.0%. The high strength property of M-AAS associated with its hydration products and Interfacial Transition Zoo. The main hydration products of M-AAS were microcline and CSH, no calcium hydroxide was found. The coexistence of microcline and CSH worked as micro-aggregate by each other, and no weak ITZ, both resulted in its high strength. The regression of its strength was related to its high shrinkage property, because the crazing caused by shrinkage would decrease the strength, especially the flexural strength.

M-AAS强度较高，但长期抗折强度倒缩。3天抗折和抗压强度分别可超过8MPa和78MPa，90天抗压强度在100MPa左右，但90天抗折强度比28天抗折强度相比低19.0％。M-AAS的高强特性与其水化产物和界面过渡区有关，M-AAS的水化产物主要为微斜长石和CSH凝胶，没有氢氧化钙，微斜长石与CSH凝胶相互填充和配合共同起到强度的作用，M-AAS砂浆中几乎没有发现界面过渡薄弱区。M-AAS的强度倒缩现象与其收缩值较大有关，收缩会引起M-AAS硬化体内部出现微裂缝，使强度下降。

结果表明：当截面形状不变且为正多边形时，各尺寸参数只与折痕宽度有关；随着折痕宽度的增大，所有参数都按比例同步增大，即该类新型纸容器的各折边长度尺寸由截面形状及折痕宽度唯一确定。

Hand-folded four-Pack (50g/mdoes-quadratical and the following paper) or hand-fold three fold (60-80g/m-squared paper) in a manner worthy of the books which should be in the book-to-last three fold in a manner worthy of the fold sewup hemomediastinum, to rule out the air and in a manner worthy of the book to prevent wrinkles appear, but now there are many flats in manual folding, knowing very well that should be hemomediastinum, but the pursuit of production would go for the big is not hemomediastinum, and finally after the wrinkles in buchbinderei and unrectifiable is extremely serious.

手工折四折（50g/m平方及以下的纸张）或手工折三折（60-80g/m平方纸张）的书帖均应在书帖倒数第三折折缝上破口，以排除书帖内空气而防止皱褶出现，但现在有许多单位在手工折页时，明知应破口，但一味追求产量就是不破口，最后书籍装订后皱褶极为严重而无法补救。

It is found that for the same volumetric flow rate, the pressure drop in the shell side of the curved baffle heat exchanger is remarkably lower than that of the traditional one. And the pressure drop percentage deceases even more for a smaller curvature radius of the curved baffle and height of the baffle cut.
