According to the engineering practice, the theoretical basis and method that survey directly the horizontal distance and height difference by the total station system as fourth grade and below fourth grade control network are put forward instead of surveying slant distance and zenith distance
摘要根據工程實踐，提出了用全站儀直接測量平距、高差來代替測斜距、天頂距作四等及四等以下控制網測量的理論依據和方法，並以張河灣抽水蓄能電站施工控制網為例進行了比較計算。If increasing drawing interval, the movement and flow range of top coal will enlarge, and the velocity gradient on flow cross - section will diminish, so that it is good for controlling the flow rate of thin sand among loose top coal
研究表明，加大放煤步距，頂煤運移流動的范圍變大，流動斷面內速度梯度變小，有利於控制細砂的下竄速度。With regard to the second phase water supply pipe project of no. 4 dongguang waterworks, an introduction was given to the selection of pipe jacking system, measures for resistance alleviation, application of intermediate jacking room, and control of axes in jacking construction of long distance steel pipe with large caliber, these may provide the reference for the construction of resembling project
摘要結合東莞市第四水廠二期給水管道工程過107國道段的頂管施工，介紹了大口徑鋼管進行長距離頂進施工時頂管機的選型、減阻措施的選用、中繼間的運用、軸線控制等問題，可供以後同類工程參考和借鑒。The test results show that the drawing interval of 1. 5 m is helpful for controlling dead - unconsolidated thin sandstone of coal seam roof and reduce sand ratio of drawn top - coal
試驗結果表明，放煤步距採用三采一放有利於控制頂板極鬆散細砂巖，降低放出頂煤的含砂率。The general idea behind the second one is approximation. the control mesh is subdivided until the error between the control vertices and corresponding subdivision surface is less than a given threshold. then the vertices substitute those points on the surface approximately. the last step is to calculate offset point for every vertex and connect them to form an offset surface
第二種演算法採用逼近思想，首先通過對控制網格進行細分，當控制頂點和細分曲面的距離滿足一定誤差要求時，近似用控制頂點代替細分曲面上的點，然後對各個頂點分別求等距點。Bearing capacity and displacement are two main problems in the application of geotechnical engineering. based on a series of pull - out tests using three kinds of paper and a sort of window screening as geogrid, twenty - seven in limit and several in working - stress geogrid - reinforced slope model tests designed through orthogonal principle have been conducted to have obtained the relationship between the bearing capacity and four factors ( i. e. reinforcement, angle of reinforced slope, the designed - length of reinforcement and the distance between layers of reinforcement ). the law of slope lateral ( horizontal ) displacement versus to the height of slope vary with external - load was derived from the model test data, and the main factor affecting the lateral and vertical displacement of geogrid - reinforced slope was obtained through analysis
承載力（強度）和變形是巖土工程應用領域的兩大主要問題，本文以紙和窗紗布模擬加筋土邊坡的土工格柵，在一系列拉拔試驗的基礎上，以正交設計理論分別安排27個極限應力狀態和若干個工作應力狀態加筋土邊坡模型試驗，並以模型試驗獲得的數據為依據，採用誤差、極差及回歸分析方法，探討了加筋土邊坡承載力與筋類、筋長、層間距、坡角4因素的相關關系，獲得了在外荷載作用下加筋土邊坡的側向位移隨坡高的變化規律（並進行了定性解釋）和坡頂的豎向位移特性，並分析其主要控制因素。Gets or sets the padding width for the top edge of a docked control
獲取或設置停靠控制項的頂邊緣的邊距寬度。The slide mechanism mainly by pushing for and the hydraulic power system with the necessary supporting wireless sensor detection and computer control system and network components, equipment is small in size, light forces, carrying capacity, a high degree of automation, convenient operation flexibility, security and reliability, the slip lifting the weight of components, and standard features such as unlimited distance
連續頂推機器人主要由頂推器、液壓動力系統以及與之配套的傳感檢測和計算機無線和網路控制系統等組成，具有設備體積小、自重輕、承載能力大，自動化程度高，操作方便靈活，安全可靠性好，被滑移、頂升構件的重量、尺度和距離不受限制等特點。分享友人
