摘要利用大型竖井模拟试验台，对冲积层疏排水过程中立井井壁受到的竖直附加力的变化规律开展了模拟试验研究。 |
| 9. | On the basis of the analysis of the test data , the additional force linearly increased with variation of water pressure in the aquifer , and increased with the increase of the depth and with the content of coarse soil particle in the overburden layer
试验结果表明：竖直附加力随含水层降压量的增大而线性增加，随深度增大而增大，随土层中粗颗粒含量增多而增大。 |
| 10. | The technology , which is developed on the basis of perfora ting techniques for oil wells and cement injection techniques , can not shoot thr ough the frozen pipe wall at predetermined ground location using energy - gatheri ng - blasting techniques , but also consolidate shaft wall rock by cement injectio n and filling along the frozen pipe and perforated hole s trajectories , achievi ng leakageproof of shaft walls and reducing vertically - added force
它利用聚能射孔爆破技术，在预定地层位置将冻结管射穿，同时在地面利用冻结管及射孔弹道对特定地层进行注浆充填加固，既可实现井壁堵漏，又能减少由于地层沉降对井壁的垂直附加力。 |
