Based on the deep foundation pit project of tunnel in Nanjing metro west extending line, the supporting methods of the bored pile biting into deep mixing pile in soft soil are discussed. The key construction techniques and monitoring results for the supporting form in watered and soft soil bed are expounded. The ability of resisting seepage must be considered when insertion depth of supporting structure is designed, which may also prevent the skirting from losing its stability.

A software for aided designing bolt of tunnel named ANSYSBOLT was designed on the basis of ANSYS finite element software. In the software environment, bolt supporting model of physical tunnel in tectonic stress field was structured according to physical parameters of coal and rock seam of some working face, and in conditions of different buried depth, bolt supporting structure and pre-tightening force, distributions of stress of surrounding rock of physical tunnel and its displacement were analyzed and calculated by ANSYSBOLT software. Then influence of different buried depth, bolt supporting structure and pre-tightening force on stability of roof and floor of tunnel was analyzed and finally feasible scheme of bolt supporting was gotten according to the analysis result.

将机床主轴转速调整到稳定区工作不但可以使切削过程稳定，获得优良的加工表面，而且可以通过进一步增大切削深度提高机床切削效率，本文对优控主轴转速下机床切削系统的极限切削深度进行了试验考证。

In the process of building and using the mass concrete structures, because of the effect of out-side condition and themselves, some faults will form in the structure, these faults will effect the bearing capability and endurance Using nondestructive testing method to test the concrete"s quality and diagnose its healthy, which has the significant sense in assessing the safety stability and research of the administering diseasesThis dissertation mostly researched the testing methods in the mass concrete structure, discussed the principles, methods, features, sphere of application of the ultrasonic testing in the mass concrete structure with faults, used dynamic FEM to simulate the testing process, discussed when the concrete structure with cracks is under the effect of the pulse, how the elastic waves propagate and what are their changing feature, Researched the principles of the first-arriving waves" phase when the cracks" depths are not same, obtained the relation between the inversion point and the cracks" depth, which has the direction sense in the application of projects,The second part of this dissertation is CT , which used the ultrasonic wave running through the tested-substance to get arriving-time of the ultrasonic wave, then inverse the image This dissertation drawed one CT program which can well present the different little cells ultrasonic wave velocity profiles of the substance, thereby to diagnose the quality of the part of the tested-substance, CT has the better using foreground..

在混凝土结构的施工及使用过程中，由于受其自身及外界各种因素的影响，常常会产生一些缺陷，对结构物的承载能力和耐久性造成严重影响，采用无损检测技术进行质量检测和健康诊断，这对混凝土结构开展安全、稳定性评估以及病害隐患治理研究具有重要意义。本论文主要针对大体积混凝土结构缺陷的检测方法展开研究工作，重点讨论了超声波法检测混凝土结构裂缝的基本原理和方法及其特点、适用范围，运用动力有限元数值模拟其检测过程，探讨了有裂缝缺陷的混凝土结构在脉冲荷载作用下弹性波的传播及其变化特征，研究了不同裂缝深度下首波相位变化规律，得出了反转临界点与裂缝深度之间的关系，这对实际工程应用具有指导意义。声波CT是一种新的无损检测技术，它是利用声波穿透被检测体获取声波接收时间，来进行计算机反演成像的技术。本文利用直射线法编制了层析成像程序，能较好地呈现被检测物体各微小单元的声波速度分布图像，从而对检测体的质量状况作出诊断评估，具有较好的应用发展前景。
