1) Guodikeng Formation
锅底坑组
1.
Through ostracoda biostratigraphical investigation on the continental Permo—Triassic transition suc- cession from the south limb of the Dalongkou anticline section in Jimsar,Xinjian found very abundant ostracoda fos- sils in the Guodikeng Formation.
通过对新疆吉木萨尔大龙口背斜南翼剖面,陆相二叠系—三叠系界线层段锅底坑组介形虫生物地层的研究,发现介形虫化石非常丰富,计有3属51种,可明显地划分为两个组合带,即①Panxiania reticulata -Darwinuloides circulosa-Darwinula parallela 组合带和② Darwinula rotundata-Darwinula gloria-Darwinula pseudooblonga 组合带。
2) inclined well in open-pit
坑底斜井
3) bottom excavation
坑底施工
1.
Controlling the lateral deformation of retaining wall is one of the hot issues in deep excavation,and the lateral deformation during bottom excavation occupies considerable proportion of that in the whole excavation works.
分析结果表明,坑底土体暴露时间对土体暴露期间及整个坑底施工阶段的基坑变形有着显著影响,随着坑底土体暴露时间的延长,坑底施工阶段墙体变形量可达总变形的30%,缩短土体暴露时间是控制坑底施工阶段围护墙变形的关键。
4) pit bottom soil
坑底土体
1.
Results show that exposure time of pit bottom soil affects notably the diaphragm wall displacement during the periods of both soil exposure and pit bottom construction.
根据上海某地铁车站基坑变形实测数据及跟踪工况,对坑底土体不同暴露时间情况下围护墙体变形的情况进行分析。
6) abrasion dents on floor
底板冲坑
