鉆孔中距
英文
pitch of holes-
The structure of the modern woodwork, processing quality has proposed higher demand to the wood processing equipment, for instance : wooden tenon position public errand, hole of interval, modes in chinese operatic music of furniture must high many rows of drill is it realize to come very by precision, panel unloading to is it realize to come by accurate person who cuts out board, is it is it is it is it sharpen by accurate numerical control machining center is it realize to come to mill to process to pare to milling extremely high of imitating etc.
現代建築裝飾及家具行業的發展與加工設備是休戚相關的。現代木製品的結構加工質量對木材加工設備提出了較高的要求，如：板式傢具的木榫孔間距的位置公差必須由精度很高的多排鉆來實現，板材下料是由精密裁板機來實現，仿型極高的銑削加工是由精密數控銑削加工中心來實現的。The quantification indexes that token weathered degree are primary velocity, borehole rqd ( rock quality designation ), joint space, joint number and so on, and the unloading ones are primary velocity, joint opening, borehole penetrability and so on. the compartmentalization of different weathered and load - off zones according to quantification indexes tallies with the slope geo - stress computed by finite element method
其中研究風化分帶的定量指標有縱波速vp 、鉆孔rqd 、結構面間距與條數等，研究卸荷分帶的定量指標有縱波速度、節理開度與鉆孔巖體透水性，據此劃分的不同程度風化、卸荷巖體與有限元計算的壩區河谷應力場具有良好對應性。Associated with a practical example of pipeline crossing with directional drilling technique in yizheng - changling crude oil pipeline, this paper analyzes the characteristics of crossing through rocky stratum with directional drilling, deliberates the stratum status, drilling machine selection, drilling tool assembly, direction control, mud control ; drilling process as well as emergency dealing scenarios at the stages of guiding - hole drilling, aperture expanding and back - towing
摘要結合儀征長嶺原油管道洪湖長江定向鉆穿越工程實例，分析了管道定向鉆穿越長距離巖石層的特點，論述了定向鉆穿越巖石層的地層狀況、鉆具組合、控向措施、泥漿控制、鉆進工藝以及導向孔鉆進、擴孔、回拖階段的應急預案，針對在鉆導向孔過程中因泥漿壓力高、信號線多次出現被高壓泥漿沖壞、造成控向信號不穩定甚至中斷的情況，對信號線的安裝提出了改進措施。This paper looks soil as homogeneous stationary random fields, expatiates the application of the random process in the geotechnical engineering and establishes the basic concept, its assortment and digital feature of random process and random fields, tests whether this random fields is a stationary process and whether it is ergodic, applies correlation function theory and variable function theory in the study of the random fields of soil parameter, acquires the relation of the two theories and draws the conclusion that they are equal essentially, fits the measured curve by using the correlation function method, variable function method and other methods, and acquires the value of correlation distance, applies the random fields theory of soil parameter in actual engineering, estimates the value of elevation and other soil parameters of 92 holes in baoding city and the results are satisfying
將相關函數理論和變異函數理論分別應用於巖土參數隨機場的研究中，通過運用這兩種理論對巖土參數特性的描述，得出這兩種理論的內在聯系及其本質一致性的結論。分別運用相關函數法、變異函數法及其它求解相關距離的方法對實測函數曲線的擬合，得出描述空間相關程度的度量? ?相關距離（或變程） ，對用這幾種不同方法得出的相關距離（或變程）值進行了比較，並對這幾種方法的優劣和實用性做了評比。將巖土參數隨機場理論運用於工程實際，對保定市區某場地的92個鉆孔的各層位的層底標高及其它幾種常見的巖土參數做出了估計，預測結果比較令人滿意。分享友人
