Standard test method for determining deformability and strength of weak rock by an in situ uniaxial compressive test
現場單軸壓縮試驗測定軟巖石的可加工性和強度的標準試驗方法According the field test of conduit with high embankment, this paper states the main cause of conduit damage is that the formula or the experience curves with a smaller earth. value of the top of conduit from calculation are used. in order to get rid of the damage the better means is that soft material paved on the top of conduit
涵洞(管)縱向開裂病害存在非常普遍,本文結合高填土涵洞現場測試,指出一些設計部門採用了計算值偏小的公式或經驗曲線計算涵洞頂的垂直土壓力,是病害產生的主要原因,較好的解決措施是在涵洞頂鋪填壓縮性大於填土的柔性材料,可以大大減小洞頂垂直土壓力。In this article, through lab and engineering site trials that the physical data of new type pipe materials is corrected, the results are as follow : ( l ) the expansion coefficient of new plastic pipe materials is more large than that of iron pipe. ( 2 ) new plastic pipe materials have different heat - resisting character and according to the water temperature to choose pipe materials ; ( 3 ) the loss of head of water for new type pipe materials is more smaller than iron pipe and also correct the loss of head of water that calculated by theory ; ( 4 ) probing into the press - resistance character of new plastic pipe materials
本文通過試驗室試驗及工程現場試驗,對新型給排水管材的幾個重要的物理性能參數進行實驗測定,糾正了以往的錯誤認識。研究結果表明: ( 1 )新型塑料管材線脹系數遠遠大於鋼管和鑄鐵管,設計和施工中要嚴格考慮管道的伸縮; ( 2 )新型塑料管材耐高溫性能各不相同,需根據管內水溫選定管材; ( 3 )新型管材水頭損失遠小於鋼管,並對原水頭損失計算公式進行了修正; ( 4 )對于塑料管材的耐壓性能進行了探討。In large rotating machinery using filmatic bearing ( turbogenerator, air compressor, etc. ) there is a potential trouble from impefect installation or running conditions, a metals " contact between rotors and shells. the trouble is usully called rubbing. the advantage of ae technologe in the rubbing diagnosis and early detection is showed. instead of classical ae characteristic parameters ( counts, amplitude, energy, duration and the other ones ) a new feature extraction by frequency analysis of ae envelop signals is discussed. both research of ae process and field experements indicate that periodic components in the envelop spectrum related to rotational speed increase evidently at the beginning of rubbing production, hence are highly sensitive to the rubbing fault diagnosis. according to the new design an acoustic emission equipment for the rubbing diagnosis named buaa ae testing system is developed and described
汽輪發電機、空氣壓縮機等採用油膜支撐的大型轉動機械,由於安裝或運行中的原因,在轉子旋轉過程中,可能和器壁發生輕微的摩擦和碰擊,簡稱碰摩.聲發射技術在碰摩發生特別是故障早期診斷上有優越性.本系統的特點是沒有沿用傳統的計數、幅度、能量和持續時間等聲發射特性參數,而是在聲發射包絡信號的頻率分析中進行特徵提取.聲發射發生的過程分析和現場試驗都表明這種方法對碰摩檢測很敏感,在碰摩發生的起始階段,包絡譜中與轉速同步的周期性分量顯著增加.根據這種新的設計思想自行研製了buaa碰摩聲發射檢測儀並對此作了介紹Large - dimension compression tests are performed in laboratory and void ratio ? epth curve are obtained by means of in - situ sampling. by comparison of in - situ tests results and laboratory tests results, an opinion that organic biodecomposition does n ' t change the void ratio of msw during compression by and large is proposed
