 bidirectional stress
 A bidirectional stress gage is employed in the new shear device.
 After a completion of a freezing shaft liner construction, due to the thaw of freezing soil and subsidence of ground, a first negative frictional force was occured. A second frictional force was occured due to coal mining, mine water drainage, water table dropping in overburden, ground surface subsidence, ground compression and subsidence. Due to the seasonal exchanges and high temperature in summer, there is a temperature stress in the shaft liner and there is a negative frictional force in the shaft liner.... After a completion of a freezing shaft liner construction, due to the thaw of freezing soil and subsidence of ground, a first negative frictional force was occured. A second frictional force was occured due to coal mining, mine water drainage, water table dropping in overburden, ground surface subsidence, ground compression and subsidence. Due to the seasonal exchanges and high temperature in summer, there is a temperature stress in the shaft liner and there is a negative frictional force in the shaft liner. The present calculation of the frictional force is based on a pillar foundation and has some disadvantages. It is assumed that the negative frictional force along the surface of the freezing shaft liner are evenly distributed. Except the other loads, it only calculated the net weight of the shaft liner. It is to define that the failure stress due to the failure depth of overburden and bidirectional stress of shaft liner concrete is 1. 2 higher than the unidirectional stress. The negative frictional force at the shaft failure is calculated with a reverse calculationa method. Based on 10 failure shaft liner in Huibei and Datun coal mining areas as examples. records of certain data and in consideration of a safety figure, it has defined a negative frictional force for mine shaft liner in Huibei, Datun and Xuhui coal mining areas by using math statistical method. The negative frictional force can be used for the design of mine shaft liner. 论述立井井壁纵向负摩擦力存在的依据,目前计算负摩擦力以桩基为基础的计算方法存在欠缺,根据一定假设、井壁自重应力、井壁破坏深度和破坏应力,反算法推算出负摩擦力,再用数理统计和考虑适当偏安全,求出淮北、大屯和徐淮矿区立井井■摩擦力的建议值。 The main cause to produce longitudinal cracks on annular section concrete poles is studied. It is considered that some points in the pole are in the state of compression - tension bidirectional stresses due to combined actions of compression, temperature and dry - shrinking stresses,and this state leads to form longitudinal cracks. The theoretical analysis of force enduring state in the pole is made through tests,and 4 measures to prevent the longitudinal cracks of pole are submitted. 对环形截面混凝土电杆纵裂产生的主要原因进行了研究,认为:主要由于压应力、温度及干缩应力的共同作用,使电杆中有些点处于压—拉双向应力作用状态,导致纵裂产生。并通过试验,对电杆受力情况进行了理论分析,从而提出了防止电杆纵裂的4点措施。 Coiled Tubing( CT) is getting more and more attentions as a simple and quick snubbing unit in oil/gas fields. There are tensile force, compressive force, external or internal hydraulic pressure and other force acting on CT as the string is being either run into the hole or being pulled out of the hole. And CT has characteri- stics of light and soft compared with drilling tools and regular tubings. Thus, the property and quality of CT is very important for CT operating. In order to avoid yield...
