1) pile-group support
轨排井
1.
There existed security problems to install pre-tensioned cables on the south side of the pile-group supported foundation pit on Line 3 of Shenzhen subway, and it was difficult to drive perforated steel pipes.
针对深圳地铁3号线轨排井基坑施工中预应力锚索存在的安全隐患,考虑设计中的钢花管施工难度较大等原因,结合实际揭露地层,利用有限差分分析程序FLAC3D进行优化设计。
2) track panel shaft
下轨排竖井
1.
During metro construction a track laying out base should be set up and accordingly,a track panel shaft should be set up in the mining interval,such shaft has deep depth and large cross section without lateral support in the middle.
地铁区间须设置铺轨基地,在暗挖区间相应的要设置下轨排竖井,竖井埋深大,断面也较大,中间不能设横撑,这些控制因素使下轨排竖井设计难度较大,通过广州地铁三号线体育西路站至珠江新城站区间的下轨排竖井设计和施工实践,介绍了暗挖区间下轨排竖井设计的方案和相应的基坑围护措施,可为今后类似工程提供设计参考。
5) bottom hole trace
井底轨迹
6) hole trajectory
井眼轨迹
1.
3D visualization of hole trajectory in directional well drilling
定向井实钻井眼轨迹三维可视化描述
2.
MWD had been used to monitor hole trajectory.
曙1区杜84-兴H73水平井由于受邻井的限制,施工难度很大,为此利用MWD随钻监测井眼轨迹,施工中通过变换钻具组合、调整钻进方式、改变钻进参数及防碰绕障等技术和方法准确有效地控制井眼轨迹,达到钻井目的。
3.
During the drilling, it is difficult to accurately measure or describe a great deal of influencing factors on hole trajectory.
井眼轨迹形成过程中,影响轨迹的许多因素都难于精确测量或精确描述,这些不确定因素对井眼轨迹综合作用是随机的、不确定的。
