joint spacing 中文意思是什麼
joint spacing
解釋
節理間距-
Although joint spacing is an important index in rock mass structure classification, it ca n ' t be obtained in some regions such as riverbed, so the practicability of using those indexes which characterizing the integrity degree of rock mass to class the rock mass structure is studied, and good coincidence is shown in rock mass structure classification by joint spacing, integrity coefficient and number of joints in dam abutment
本文研究了用表徵巖體完整程度的指標?完整性系數、 rqd及5m洞段節理條數j _ d （與體積節理數類似）劃分巖體結構類型的可行性。對兩岸壩肩部位，節理間距、完整性系數、 5m洞段節理條數這三項指標劃分的巖體結構類型基本一致；河床壩基部位主要用rqd指標來判斷巖體結構類型。 -
In this paper, a three dimensional finite element analysis has been used to analyse the loading stress of utw pavement. the critical loading position of utw plate and the rules of the effect of the joint spacing of plate, the thickness of overlay, ec / es and the interface conditions between concrete overlay and existing ac on the stress are provided
本文採用三維有限元法分析了utw路面荷載應力，確定了路面板的臨界荷位，得出了板接縫間距、厚度、板與地基模量比（ ec es ）和層間接觸狀況對應力的影響規律。 -
After contrasting and analyzing the two common used measure method of discontinuity, a modified method that is elaborate method of joint surveying is put forward for the first time. rational method to get spacing of joints is researched utilizing lots of statistical results. according to the theory of minimal valid length of scanline, 5m is chose as appropriate statistical section length to obtain the successive values of those indices indicating rock mass structure, they are spacing, number and total length of joint
本文在對比分析目前兩種常用的結構面測量方法優缺點基礎上，首次提出了一種改進的結構面測量方法?節理詳細精測法，並利用大量的統計結果，研究合理的間距取值方法，根據間距無偏差測量的最小有效測線長度理論，選擇5m作為統計區間長度，獲得了節理間距、條數、總長度隨洞深的連續變化值。 -
Compared with the experiment data, the temperature field and the thermal stress field are discussed. the spacing, the time of sealing and the plane form of the later joint - filled slots are discussed especially, and it is found that the spacing, the time of sealing and the plane form of the later joint - filled slots are comprehensive indexes which are relevant to material, design and construction. the theory value of the spacing and the time sealing of the later joint - filled slots and some proposals on the plane form are presented on the basis of numerical calculation
本文在綜合前輩的研究成果的基礎上，推導了粘彈性場的三維有限元解，對比實際工程實驗數據，對大體積混凝土結構內部的溫度場和應力場進行了分項研究，重點討論了后澆帶的留置間距、封閉時間和平面形狀，發現其留置間距、封閉時間和平面形狀都是綜合指標，是和材料、設計、施工有關的。 -
If the ratio of joint length divided by joint spacing is less than 10, the rock mass is likely connected
