Abstract:It is always important to research building incline and cracking induced by differential settlement around foundation pit. Base on current computing method of ground settlement, ground settlement and building settlement induced by supporting, excavation and precipitation of foundation pit are analyzed by means of a finite element elastoplastic model with the engineering example. Numerical results indicate that the greater effect is induced by supporting and there is 20 mm’s difference between with or without taking account of precipitation. At last the main measures are given to reduce settlement.

Abstract:The failure of anti-friction rings on drilling pipes at Northern Erdos Work Areas is very in common. The main causes of the failures of the anti-friction rings on drilling pipes are formation abrasion, downhole performance conditions of drilling pipes, selection of high-abrasive materials, and welding techniques. It is very important to resolve the problems of anti-friction ring failure due to partial worn at Northern Erdos Work Areas by reasonable selection of high-abrasive materials and welding techniques.
