Setting up city track transportation system is the way to solve the traffic in the cities, and to realize substanable development. There have tow reasons: first, city track transportation has many merits, great capability, quick speed, safety on time, low cost, saving energy, catabatic traffic block on the ground, protecting the environment and so on; second, though track transportation, the develop derection of city constructure turns from single-center homocentric cirlarity mode to multi-center axes mode.

修建城市轨道交通是解决当前大城市交通问题、实现可持续发展的有效手段，其表现有二：第一，城市轨道交通具有运能大、速度快、安全准时、成本低、节约能源、能缓解地面交通拥挤和有利于环境保护等优点；第二，城市轨道交通的修建使城市结构的发展方向从单中心同心圆结构转向多中心轴线式结构。

In order to extract cophasal axes more continuous and immune to noise, a novel approach is developed based on edge detection.

实验结果表明应用该方法可以提取连续、准确的同相轴。

Cophasal axes on seismic sections play an important role in geologic stratification, fault interpretation, detection of cavities and other anomalous bodies in geophysical prospecting.

地球物理勘探中，地震剖面中的同相轴对地质分层、断层解释、有无形成空洞以及其它异常体的检测中作用重要。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise.

由于边缘检测中常用的Sobel算子和Canny算子检测同相轴时对噪声免疫差，常因噪声因素引起边缘信息缺失导致同相轴提取不连续，本文采用中值滤波并对Sobel算子进行改进，对地震剖面图进行预处理，结合均方差自动确定阈值并进行异常检测，提取完整同相轴。

The reliability of analysis result depends largely on the in-house experimental conditions. Unlike the previous analysis that only concerns the sole effect of permeable pressure, this article considers both permeable and confining pressure and deformation characteristics of concrete material under the interaction of them according to the real work state of construction, which may leads to the changing pattern of permeable rate as listed below: permeable rate always reaches its peak with the time process going on, than goes down and remains straight on some certain value; The PR will tend to decline while the confining pressure is increased, and the time taken before the peak will be extended as well; Under the constant permeable pressure and circularly changing confining pressure, the minus-exponential ascend and descend relationship could be applied between the PR and Time axes respectively with crannied and intact concrete samples, and the PR of crannied concrete is far more larger than that of intact concrete. The change pattern of concrete could also be mathematically analogized using the least square method.

室内的实验条件是研究成果可靠性的重要因素，而以往的研究都只考虑了渗透压单一作用，本文根据混凝土结构的实际工作状态，同时考虑了围压与渗透压共同作用下的混凝土材料的渗透性变化特征，得出了混凝土材料在围压作用与渗透压共同作用下的渗透率的变化规律：渗透率都是随时间推移先达到一个峰值，再降低并趋于平稳；渗透率会随围压的增大而减小，并且峰值的到达时间也会随之延长；在渗透压不变，围压升降循环的情况下，有裂缝、无裂缝混凝土的渗透率变化规律是随时间成负指数关系上升、下降，且有裂缝混凝土试件的渗透率远远高于无裂缝混凝土的渗透率，并对混凝土的变化规律运用最小二乘法进行数学拟合。
