失稳

The results show that the ultimate stability bearing load by nonlinear analysis is close to the test load, they only have 10% deviation. For steel bridge towers, the correlation of the panels in the section of rectangle with chamfers is more obvious than that in the section of rectangle. If the four angles of the rectangle section were cut off, a panel with the smaller ratio of width to thickness forms, which can supply effective constraint to other weak panels with the larger ratio of width to thickness.

结果表明：第2类稳定计算得到的失稳极限荷载与实测荷载较为接近，两者相差10%；带切角矩形截面钢桥塔较矩形截面钢桥塔板件间的相关作用更加明显，对矩形截面钢桥塔进行切角，形成宽厚比较小的壁板，可以对宽厚比较大的弱板提供有效约束。

由于外压增量导致环板内塑性区域扩展的范围小于等值内压的影响，因此可以定性的认为，在同样的轴向压缩量下，波纹管的平面失稳外压临界压力大于内压临界压力。

Considering the theory of roadway support in soft rock, we proposed an active support mode based on study of rheology of weak adjacent rock, complex stress environment, and destabilization of original supports. Fully grouted bolt, extension grouted cable that can strengthen self-bearing capacity and entirety are used. Original support scheme and reinforcement scheme are simulated by means of FLAC(superscript 3D).

块体可能的失稳方式主要为拱顶直接掉落、拱腰和边墙部位出现单滑面或双滑面滑动块体。

Rockburst is a mine seism that is caused to happen by mining, it is one of natural calamities. It is a dynamic phenomenon, the coal and rock mass or fault in high stress area releases a large of energy when it is disturbed and instability destroy instantaneously, and its characteristic is volcanic shake and explosive destroy.

冲击地压是采矿诱发的矿井地震，是矿井的一大自然灾害，是指矿井高应力区内煤体、岩体及断层在受外界扰动瞬间失稳破坏时，释放出很大能量而引起的以猛烈震动和爆发式破坏为特征的矿山动力现象。

Based on the testing analysis of microcosmic digital image, there are smaller Fissions, higher density and even distribution under high confining pressure than under low one. Microcosmic damage mechanics of rock cracking under high confining pressure and hydraulic pressure is given. Reliable testing basis is offered to analyze further failure and stability of the noncircular cave surrounding rock under high confining pressure and high hydraulic pressure.

通过微观数字图像试验分析发现，高围压条件下大理岩断口裂纹长度小、密度大、分布相对均匀，给出高水压高围压作用下岩石破裂产生的微观损伤力学机理，为进一步分析高围压高内外水压条件下非圆形洞室围岩失稳破坏机理提供了可靠的试验依据。

Here, harsh socio-economic conditions and racial discrimination are exacerbated by health and safety hazards posed by a high water table and unstable ground.

在这里，高水位和地基失稳所造成的健康和安全危险，加剧了严峻的社会－经济状况和种族歧视。

The paper analyze the influence factor in water level, ground-water, river current, ground structure, bank aspects, wave action and vegetation condition with qualitative method.

分析得出：区域(1)-a库岸再造的主要影响因素是河道纵向水流的冲刷作用；区域(1)库岸再造的影响因素是高水位时波浪的冲刷，水位降落时覆土层的剥离，以及水位变化造成基岩的风化、崩塌；区域(2)、区域(3)库岸再造的主要影响因素是暴雨和水位降落时岸坡的失稳滑塌，次要影响因素是高水位时波浪的冲刷，水位降落时覆土层的剥离，水位变化造成基岩的风化；区域：(4)库岸再造的影响因素是高水位时波浪的冲刷，水位降落时覆土层的剥离。

The research indicates that when the gusset plate connections to slotted tubes member is used in practice, the rigidity of the member must be strengthened to avoid the happening of the whole buckling failure, and the combination of welded hollow spherical joints and gusset plate connection to slotted tubes member proves to be effective.

实际工程中应用管板连接构件作为受压构件时，必须加强构件弱轴的刚度，以避免整体失稳破坏，而采用焊接空心球补强是一种有效的方法。
