中文拼音 [xiēxíngdekuāi]
楔形地塊
英文
wedge-shaped block-
The characteristics of high pressure gyratory sprayed pumping discusses is presented, which is applicable in wide range of scope and ground layers, convenient for construction, long durability, wide source of materials. mechanism for subgrade strengthening : complex foundation of cement solid and earth between piles was formed by pulsant load of flowing pressure and spraying flow, water wallop, cavitation phenomenon, water wedge effect, extrusion force and air flow agitation etc so as to enhance foundation bearing force and reduce settlement and deformation
高壓旋噴注漿技術具有適用范圍、適用地層較廣，施工方便，耐久性好，材料廣闊等特點；其加固地基機理主要是通過流動壓、噴射流的脈動負荷、水塊的沖擊力、空穴現象、水楔效應、擠壓力、氣流攪動等效應形成水泥固結體與樁間土的復合地基，從而提高地基承載力，減少沉降變形。Firstly, according to the natural geology study of the quarry, the control structure planes are determined, which are cut to be building blocks by two sets of main joints. failure can occur due to the intensity weaken of the joint planes caused by excavation relief and rain immersion
首先研究了采場的自然地質條件，確定了影響邊坡穩定的控制性結構面，即塊體主要由兩組節理切割而成楔形體，由於開挖卸荷及雨水浸泡，致使節理面強度減弱而發生破壞。Secondly, the finite - element analysis on the typical slope section is performed with establishment of geology model, definition of boundary condition and proper selection of mechanical parameters. the result shows that the slope is of integral stability, and the failure mode mainly comprises infrequent block drop and wedge body breakage. considering the two failure modes of plane failure and wedge body breakage, and stability calculation under different work conditions, the slope stability is discussed and the sensibility ana lysis on its fraction angel and cohesion force is made
然後通過建立地質模型、確定邊界條件、選擇合理的力學參數，取典型斷面對邊坡進行數值分析，分析結果表明斜坡整體是穩定的，破壞類型以零星掉塊和楔體失穩下滑為主；為了定量計算邊坡的穩定性，對邊坡兩種破壞類型：單滑面下滑和雙滑面楔形體下滑，考慮不同工況進行穩定性計算，並對摩擦角和粘聚力進行穩定的敏感性分析。In the light of all kinds of structural faces and their assembles along tunnel, the place and growth depth of instable cuneiform body in tunnel wall rock could be predicted, then its volume and weight of instable cuneiform body are estimated based on the equator plane projecting method and the solid body ratio geometry method, which offers reliable geologic data for designing corresponding supporting measure
摘要利用赤平投影法和實體比例幾何法分析隧洞圍巖穩定性，根據隧洞沿線所遇結構面相互組合形式，預測隧洞圍巖不穩定楔形體的位置及其發育深度，從而估算不穩定楔形巖塊的體積和重量，為設計相應的支護措施提供可靠的地質依據。A plain or notched, often wedge - shaped piece of wood or metal designed to hold parts of a machine or structure in place or provide a bearing surface, usually adjusted by a screw or key
扁柱，夾條，凹字形楔一種平的或有凹的經常是一塊楔形的木頭或金屬，用來在一定地方夾住機器或結構的各部分或提供軸承的表面，通常是由螺絲或鑰匙來調整Curtailing emissions of methane, which today contribute about half as much to greenhouse warming as co2, may provide more than one wedge : needed is a deeper understanding of the anaerobic biological emissions from cattle, rice paddies and irrigated land
今天，甲烷對于溫室增溫的影響，幾乎相當於二氧化碳的一半，因此減少甲烷排放也可能提供一塊以上的楔形：我們需要更深入了解來自家畜、稻田及灌溉田地的厭氧生物氣體排放。分享友人
