This paper describes the shield tunnel’s in and out of the hole region’s soil reinforcement technologies, and introduces a common technique for soil reinforcement of Nanjing subway shield’s in and out of the hole region, and gives them a comparative analysis from multiple perspectives. To provide a reference basis for selection of reinforcement technology, by combining with the results of previous studies, it summarizes the in and out of the hole area’s longitudinal and transverse reinforcement range. Finally, it introduces a soil reinforcement project example of a Nanjing shield zone which used the bored pile, double-barreled churning pile and lowering technologies, and demonstrates the feasibility of this reinforcement technology which ensures the success of originating and reach of the shield. This study will have a certain guiding significance of the similar projects in the future.

后期维特根斯坦哲学――日常语言分析视域下的语法研究

安徽大学学报(哲学社会科学版) , 2010,
Abstract: 后期维特根斯坦关注日常语言的实际用法,认识到其前期逻辑分析方法的不足,并进行了猛烈的批评。他认为逻辑分析方法具有单一化、简单化、理想化等缺点,不能如实地描述日常语言的实际使用情况,因而不能满足真正哲学研究的要求。他主张真正的哲学研究运用描述和综观的方法,对日常语言实际用法作语法研究,考察不同语词的实际使用情况,注意其中的差异和类似,消除对于语言形式的不同误解,最终达到澄清哲学问题的目的。尽管遇到一些误解与诱惑,但其日常语言分析视域下的语法研究对当代哲学研究特别是日常语言学派产生了深远影响。

Abstract:
远场涡流作为涡流无损检测技术的一个重要分支,目前在各个行业的管道日常维护和安全保障中发挥着重要的作用。本文重点对有限元方法在远场涡流仿真中的应用进行了研究。首先通过建立有限元电磁仿真模型,对于远场涡流效应的基本现象,如“矢位峡谷”、“相位节点”等现象进行了仿真研究,并对其结果进行了分析。同时为进一步证实铁磁性管道中远场涡流相对于常规涡流技术的优势所在,选取分别位于远场区和近场区的内外壁缺陷进行有限元仿真和对比分析。
Remote Field Eddy Current (RFEC) is an important branch cut of eddy current nondestructive testing (NDT) technique, and is drawing more and more attention in the testing and repairing of pipes and tubes. The finite element method used for RFEC simulation was researched in this thesis with detail. Firstly, some important phenomena of RFEC technique such as “amplitude canyon” and “phase knot” were simulated and analyzed. At the same time, to clarify the superiority of RFEC technology used for ferromagnetic tube compared with conventional eddy current, differential defects in “near field” and “remote field” were chosen to simulate and analyzed; Finally, advantages of remote field eddy current for ferromagnetic tube NDT were drawn compared with conventional eddy current.
