查询词典 weak discontinuity

The stability of arch dam mainly depends on the support force of downstream rockmass behind abutment of dam. If discontinuity and weak intermitted layer is existed in rockmass, abutment of arch dam will slide probably under pulling force and shear force at the both side of dam.

拱坝的抗滑稳定主要是依靠坝端下游岩体的支承，拱坝两岸山体在拱端推力和剪力的作用下，如果岩体中存在着不利于稳定的节理、裂隙或软弱夹层，便可能引起坝肩滑动。

Analog to the discontinuous bifurcation analysis for classic elasto-plastic theory by Ottosen and Runesson et al, the sufficient and necessary conditions of weak discontinuity and strong discontinuity localization bifurcation for the strain-gradient-enhanced-damage model are obtained.

借鉴Ottosen和Runeson等的弹塑性模型不连续局部化分岔方法，对应变梯度损伤模型推导出与梯度相关的强不连续和弱不连续局部化分岔充要条件。

It is indicated that, the weak discontinuity and the micro-discontinuity have significant effects on stress intensity factors, and the micro-discontinuity is a kind of connection of interfacial mechanical property better than the weak discontinuity.

分析表明，弱/微间断性对于FGMs界面裂纹应力强度因子有着重要影响，而且微间断性是优于弱间断性的一种界面力学性能连接关系。

To reduce the weak discontinuity or to make the interface micro-discontinuous are all beneficial to the enhancement of the capacity of the FGMs interface to resist impact fracture, i.e.

减小界面的弱间断程度或使 FGMs界面具备''微间断性''，都将利于提高功能梯度双材料界面抗冲击断裂能力，在一定程度上达到界面增韧的目的。

But the rigid body limit equilibrium method can not reflect the process of progressive instability and mechanical mechanism on failure for rock mass while the nonlinear finite element method is difficult to solve the displacement discontinuity of weak structural plane.

重力坝的深层抗滑稳定分析多采用刚体极限平衡分析方法和非线性有限元法，但通常的刚体极限平衡法不能反映坝基岩体渐近失稳过程和破坏的力学机制，非线性有限元法则难以解决坝基中软弱结构面位移不连续问题。

The stability of them has an vital influence on project implementation,which is also hand in glove with discontinuity surface, for example,joints,fissure,fault and weak interbed etc.These discontinuity intersect vertically and horizontally ,which makes great difference in property between it and integrated rock.On that account,we should do deepgoing research on deformation failure mechanism and stability analysis for rock mass slopes.

节理岩体边坡的稳定性跟边坡中的不连续面的关系密切，如节理、裂隙、断层以及软弱夹层等，这些结构面纵横切割，使得岩体的性质与完整岩石大相径庭，因此，必须对节理岩体边坡的变形破坏机制和稳定性分析作深入的研究。

The complexity of the 660km discontinuity beneath MDJ shows that the subducting slab materials are piled above the discontinuity, and the existence of this discontinuity beneath HIA shows that the effect of the subducting slab on the discontinuity is very weak.

MDJ台下660km间断面的复杂性体现了俯冲带物质在660km间断面上的堆积，而HIA下660km间断面的存在情况，则表明俯冲带的影响已经相当地弱了。

The existences of these discontinuities show obvious regional characteristics that,(1) at the northern Izu-Bonin which is north to latitude of 33°, the SV-P converted phases following the phases from the 660km discontinuity are relatively weak,(2) at the southern part which is south to latitude of 29°, all phases are relatively strong, even some phases' amplitudes are comparative with those from the 660km discontinuity, and (3) at the part of Izu-Bonin between the latitude between 30°and 32°, all converted phases are relatively weak except the clear phases from the 660km discontinuity.

从各地震的波形叠加结果看，这些间断面的存在情况明显具有区域性特征：在北部，北纬33°以北在来自660km间断面的转换震相之后出现的SV-P转换震相相对较弱；在南部，北纬29°以南则各转换震相相对较强，有的幅度可以与来自660km间断面的转换震相的幅度相比；而北纬30°～32°之间除了来自660km间断面的转换震相存在比较清晰以外，后至的转换震相都相对较弱。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
