In this paper, a comparativ analysis has been carried out between celmo-geological condition and hydro-fracturing stress measurement in Xiaguan Region, Northwest Yunnan. It has been found out that they are contradictory to each other, with a reason of probably over-estimated minimum herizontal principal stress measurement.Based on the observational data and elastic dynamic theory the observational result has been analysed. It has been discovered that the vertical principal stress within shallow part of...

In this paper, a comparativ analysis has been carried out between celmo-geological condition and hydro-fracturing stress measurement in Xiaguan Region, Northwest Yunnan. It has been found out that they are contradictory to each other, with a reason of probably over-estimated minimum herizontal principal stress measurement.Based on the observational data and elastic dynamic theory the observational result has been analysed. It has been discovered that the vertical principal stress within shallow part of the region is the minimum pricipal stress. But its velocity that increases with depth is larger than the minimum horizontal principal stress. The vertical principal stress turns to be the medial stress when depth is over 400 km. The real value of the minimum horizontal principal stress can be written as 0.85 + 0.227 H (MPa), here H is depth in unit m.The present analysis indicates that errors of the minimum horizontal principal stress obtained from hy.drofracturing measurement are greater than the expected ones.

本文对滇西北下关地区的地震地质条件和水压致裂应力测量进行了对比分析。认为二者是矛盾的,其原因可能是最小水平主应力的测值偏大。本文依据测量数据和弹性力学理论对测量结果进行了分析,发现该区浅部,垂向主应力是最小主应力,但其随深度增大而增加的速度大于最小水平主应力,400米以下深度,垂向主应力转变为中间主应力。最小水平主应力的实际值可以写为0.85+0.0227H(Mpα),这里H是深度,单位是米。该分析表明,目前水压致裂测得的最小水平主应力的误差要比预料的大。

In this paper, the problem of welding pool dynamic vibration was investigated by elastic dynamic theory. And the welding pool vibration equation is set up. After proving the stability of the equation solution, the general solution of the vibration equation was obtained. Using the finite difference equation, the numerical solution of the relationship between the vibration frequency and radius R of hemispherical welding pool was solved. It presents an efficient way to detect the variation of weld penetration. The testing results of 1Cr18Ni9Ti coincide well with those by theoretical calculation.

采用弹性体力学理论,对焊接熔池波动力学进行了探讨。建立了焊接熔池波动方程。证明了波动方程解的稳定性,并获得了波动方程的通解。通过有限差分法求解了焊接熔池波动频率与焊接熔池半球体半径R之间关系的数值解。为实时检测焊接熔深变化提供了一种有效方法,采用1Cr18Ni9Ti的试验结果与理论计算结果吻合良好。
