面裂

The internal breaking, the stress transmission process, the quality variation with the change of the transformation structure features and the continuous expansion of the work-doing resulted from the weak stress of the pulsation action lower than the fatigue limit.

When analyze the stability of slopes, traditional methods often use suppose that the failure surface is circular or other typical functions.

This method overcome the problems of many supposition conditions in theory and difficulty in searching critical slip surface in 3D limiting equilibrium analysis; It uses the 3D FEM\'s stress field directly, differs from the practical value of 3D FEM strength reduction method used hypothesized load, and differs from the characteristic of the FEM with limiting equilibrium theory still to need to divide the columniation, and suppose the critical slip surface in advance.

该方法克服了三维极限平衡分析方法在理论上引入较多假设条件，且搜索临界滑裂面困难的问题；它直接采用三维有限元应力场，不同于三维有限元强度折减法基于虚拟荷载上得出的实用价值；同时异于沿用极限平衡理论的有限元法仍需要进行条柱划分，并事先假设滑裂面形状及位置的缺点。

A model is erected for Fs with logarithmic spiral sliding surface which can simulate the genuine sliding surface better than others,then the express of Fs is deduced based on the upper bound theorem of limit analisis.

采用对实际滑裂面模拟较好的对数螺旋曲线滑裂面，建立了整体稳定安全系数F_c的模型，从极限分析中的上限理论推导了整体稳定安全系数F_c的表达式。

this article has briefly analyzed some good and bad points about slip crack surface form of slope stabilities , introduced one kind of new slip crack surface form -logarithmic spiral slippery fracture in this foundation.

简要介绍一种新的土质边坡滑裂面破坏形式——对数螺旋滑裂面。

It provided the reference to improve the anti-cracking capability of high strength and high performance concrete from the point of view of constructional technology and curing requirement.The result shows that the more the binder material or sand rate, the more serious the shrinkage cracking. In the concrete with a low water-to-binder ratio, a bit of difference in the dosage of water will result in big difference on the strength and the anti-cracking capability. The occurrence of cracking is mainly at early age (before 1 day). If the surface is plastered again after 2 hours of casting, the anti-cracking capability will nicely improved.

研究结果表明：随着胶结料总量和砂率的增大，高强高性能混凝土的收缩开裂趋于严重；在水胶比较低的情况下，用水量的稍微差别对混凝土的强度和抗裂性能都具有很大的影响；掺入粉煤灰对抗裂有所改善，但是其掺量对抗裂的影响并不是呈定向规律，而是存在着最优掺量；高强高性能混凝土的裂缝主要发生在早期(1d前)，若在浇注后2个小时再次抹面可以很好地改善其抗裂性能。

A new type of slip su***ce called two dimensional quadric Bezier slip su***ce was designed.

Results: Axial scanning including vertebral arch can show spondyloschisis and other signs. These contained widened or stenosis of the spinal canal, stenosis of he lateral recess, the double margin sign, deformity of the lateral recess, the double margin sign, deformity of the intervertebral disc, denegeration of the joint facet and thickening of the ligamentum flavum. Scotty dog sign were showed in images reconstructed along the direction of vertebralarch.
