這種在半導體中挖個圓洞，把電流壓縮到兩旁狹窄通道的結構，其電阻比起沒有障礙的半導體薄片要大很多（不過後者的電阻又比有金屬圓盤的半導體來得高） 。For the construction of single - arch tunnel within cracked surrounding rocks, 8 tunnel models are set up to study the effect of the earth pressure distribution of the various surrounding rocks due to excavation. the relationships between the loosen zone of tunnel radial earth pressure and the tunnel diameter, the characteristics of surrounding rocks and the exposed time are revealed. it is showed that the pressure loosen radius is 1. 2 ~ 2. 0 tunnel diameters and the strongly loosen radius drops to 0. 5 ~ 1. 0 one for double lane tunnel
對于單拱破碎圍巖隧道的構築問題，作者設置了8個隧道模型，研究開挖對不同隧道圍巖壓力分佈的影響，揭示了洞周徑向壓力的鬆弛范圍與洞徑、圍巖特性、裸露時間的關系，得到雙車道隧道壓力鬆弛半徑為1 . 2 2 . 0倍洞徑，強烈鬆弛區半徑為0 . 5 1 . 0倍洞徑。At the end of fifteen months the level was finished, and the excavation completed beneath the gallery, and the two workmen could distinctly hear the measured tread of the sentinel as he paced to and fro over their heads
十五個月之後，地道挖成了，走廊下面的洞穴也完工了，每當哨兵在這兩個挖掘者的頭上踱來踱去的時候，他們可以清晰地聽到那均勻的腳步聲。In the simulation and analysis on culvert construction, the method of foundation - pit excavation layer by layer and step by step was used, i. e. the method that makes the surface of excavation have no stress, when the elements were excavated gradually in period of construction. at this process, the state of soil is unloading, the laws of stress field and displacement field with the depth of excavation were studied. based on the obtained stress field and displacement field after the excavation was completed, by using of the newly increased filling - elements " gravity and the grinding force, the simulation of the construction of body of the culvert and foundation - pit ' s filling layer by layer had also been done in this dissertation
用有限元法模擬分析涵洞基坑開挖時，採用分層、分步模擬開挖過程的方法，即將計算域內單元分層「挖去」 ，使開挖表面成為無應力表面的方法，分析土體在卸載狀態時的應力場和位移場隨開挖深度的變化規律；在洞體施工后，回填土體時，據開挖完成時的應力場、位移場，通過逐級增加計算域內的單元數目，施加每級新增加單元的自重荷載，利用有限元法模擬基坑及上覆土體分層填築的施工過程，這不僅反映土體處于再加載應力狀態時，填土受力及變形的一般規律，而且這種將地基? ?涵洞? ?土體作為一個統一整體進行模擬的方法，量化了三者之間的相互作用關系。As to the tunnels of jinping hydroelectric power station in sicuan province, the thesis discusses how to reasonably consider the initial stress field when designing a large - scale tunnel with high initial stress and deep buried. first, by analyzing of the rock lab tests and discusses the feature of regional geomorphology. explains the production of initial stress field, analyze the initial stress of jinping hydroelectric power station ; second, using the fem, the paper creates the real model of region. according to the results of stress measurement point, by combining of ann and fem to decide the boundary condition, the paper calculates the initial stress field ; at last, the paper analyzes the influence of the initial stress field formed from different condition on the deformation and stress of the surrounding rock, and the main factor to influence the initial stress. on the basis of the former work, the author proposes some proposals, which will be helpful for studying and designing of the similar undergroun d engineering
首先從巖體的應力?變形的特性入手，並結合工程區域的地形地貌特徵，對巖體初始地應力場的形成做出解釋，結合錦屏水電站初始地應力的現狀提出了將地應力場進行分帶；然後建立整個工程區的實體模型，在地質分析的基礎上，以工程區右半部分為代表，參照實測點的初始地應力值，採用了神經網路與有限元相結合的方法反演了該區域的初始地應力場；最後模擬隧洞的開挖，通過計算比較分析了初始地應力場對處于不同應力帶內的隧洞圍巖穩定性的影響，在此基礎上提出了作者的建議，力圖為該類工程的研究設計工作提供有益的幫助。Using the finite element method ( fem ), the simulation and analysis on this construction process were carried on, and the different stress state of soil at different construction period was rendered. and the influence of different stress paths ( foundation excavation - unloading & excavation filling - reloading ) on the stress and the displacement was also reflected and researched. the law of non - linear constitutes of soil was presented in the simulation and analysis
模擬分析再現了土體的非線性本構關系，得到了基坑開挖時土體變形和應力變化的一般規律；在基坑及上覆土體回填時，通過分層填築的有限元模擬和地基、涵洞、土體三者相互作用的有限元分析，得到施工結束太原理工大學碩士學位論文時的位移場和應力場，同時求得涵洞的結構內力。Burn holes in the ground to jump through or trap enemies to reach the exit
