然而,隨著時代發展和科技進步,人類對自身認識不斷深入,教育理念不斷地更新,學生觀得到了根本性的改變,以學生為本、尊重學生個性的教育理念已經日益深入人心,公眾對學生基本權利等一系列問題日趨關注、探討日益深入,在這種大背景下,懲罰作為一種教育方式,在教育領域中尤其在中小學教育實踐中,其應有的地位和作用史無前例的受到了來自不同層面的個體的挑戰和質疑。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。The presence of small amount of liquid at grain boundaries tends to form thin viscous layer which surrounds the finer grains. intergranular fracture may occur at the grain boundaries between two fine grains not covered by viscous phases. the high ductility achieved at low strain rates is generally attributed to dislocation glide - creep accommodation mechanisms
原始晶界上產生少量液相,形成薄的固液共存粘性層並包圍細化的晶粒,沿晶斷裂主要發生在無粘性層的細晶粒間;而在較低應變速率下,三叉晶界位錯攀援?蠕變協調機制鬆弛晶界滑移產生的應力集中,晶界上產生較多液相,有利於晶界滑移進行。In the paper, other research results are summarized, and a big test model indoor of row pile retaining and protecting deep foundation pit is designed. for homogeneous soil or samdwich soil structure three different retaining and protecting kinds : dense pile, thin pile and without pile are designed, using excavation simulation and loading on the top of slope, the model test is divided into two stages : foundation pit excavation simulation stage and destroy test stage. in this paper, for three different retaining and protecting kinds, the relation between soil pressure and displacement of piles, the relation between soil stress and strain, interaction of pile and soil and retaining and protecting loss - stability destroy are systemic studied
本文總結了前人研究成果,構築大型室內深基坑排樁支護試驗模型,在均質及層狀土層結構地基上,設計了密排樁、疏排樁及無支護三種不同支護型式,採用模擬開挖與坡頂均布加荷方式,進行了模擬基坑開挖和破壞性的兩個階段試驗,對三種不同支護型式的土壓力與樁位移、土體應力與變形、樁土共同作用及支護結構失穩破壞進行系統研究。The reflected wave will be received by the receive antenna and transferred to digital data. we can analyze the data that saved by the computer of gpr to deduce the medium ' s property, situation, location and so on. being a kind of nondestructive, untouched method, it has many advantages such as nondestructive, rapidness, simpleness and high precision, so it will have wide applications in the ways of examination, control and maintenance to road quality, especially for highway
路用探地雷達是近幾年發展起來的、應用於公路無損檢測的一項新技術,它利用超寬帶脈沖電磁波對路面結構層進行探測,當雷達發射天線發射的電磁波在路面結構層中傳播時會在介電特性突變處產生反射和透射,反射回來的波經由接收天線接收並轉化為數字信號儲存起來,通過分析探地雷達回波信號來估計路面結構層的性質、狀態和位置等特徵。So far, existing brain function evaluation techniques includes electroencephalogram ( eec ), magnetoencephalogram ( meg ), positron emission tomography ( pet ), functional magnetic resonance imaging ( fmri ) etc. among them, the technique using event - related potential ( erp ) contained in eeg features high temporal resolution, low costs and convenient application
到目前為止,探測大腦活動的方法有eeg (腦電圖) , meg (腦磁圖) , fmri (功能磁共振成像) , pet (正電子發射斷層掃描)等。其中利用包含在eeg中的erp (事件相關電位)進行的研究,能達到毫秒級的高時間解析度,而且器械成本低應用方便,對探索人腦瞬息萬變的信息處理機能(認知機能)無疑是很有幫助的一項技術。Considering that the load was added in steps, dynamic design based on in - sile test parameter is an effective and practical method. based on the author ' s experience of djm composite ground engineering, and two projects of highway djm composite ground, it systemically analyzed and summarized the in - site test result as well as the settlement deformation, pore water pressure dissipation, deep horizontal displacement, stress ratio, stress of pile. etc. it also compares the in - site test results of djm composite ground with or without rigid bearing stratum, and draws many practical conclusions
根據筆者多年粉噴樁加固路基工程的經驗,結合兩個高等級道路粉噴樁加固路基工程實例,全面系統地分析和總結了現場試驗路段試驗結果,對攪拌樁復合地基沉降特性、孔壓消散特性、深層水平位移特性、樁土應力比、樁身應變等作了深入細致地分析,對有硬持力層和無硬持力層(浮樁)的粉噴樁復合地基現場試驗結果作了對比,得到了許多有應用價值的結論。C ompared the results of structural period, displacement and internal forces of mode 1 with mode 3, we can know that the hypo - frame can increase the lateral stiffness of the mega steel - frame structures, decrease lateral - deformation of the structures, especially decrease the maximum inter - storey displacement obviously, and get the internal forces and deformation of the whole structure more uniform. from the analysis results, it can be found that the maximum axial force gets less with hypo - frame than without it, and the maximum shear force and bending moment get more with hypo - frame than without it. thus it can be seen that the mainframe can be an independent structure system by itself, but the cooperation of main and hypo frame should be considered for conducting the entire analysis and design, otherwise the mega structure can be unsafe, in addition, from the comparing analysis, it can be found that the shear force and bending moment of inside - row columns are increased much more than those of outside - row ones in a mega column
通過3個算例方案1和方案3結構周期、位移和內力反應的比較分析可知,次框架可以進一步增加巨型鋼框架結構的抗側剛度,減少結構側向變形,特別是明顯減少了結構最大層間位移,使整個結構的內力與變形分佈更為均勻;次框架的加入使主框架柱最大軸力較無次框架情況減少,而主框架柱的最大剪力和彎矩較無次框架情況都有所增加,由此可知,雖然主框架本身可以成為獨立的結構體系,但在分析設計時,還應該考慮主、次框架協同工作,進行整體分析、整體設計,否則結構會偏於不安全。分享友人
