Through design, construction and observation of a high pressure hydraulic tunnel built in the fault zone, the following problems are discussed in the paper: 1. It is appropriate to consider a part of external hydraulic pressure to balance part of internal hydraulic pressure in design of tunnel lining in the fault zone; 2. Reasonable selection of the rock mechanic parameters is extremely important for making a correct design. Incorrect selection of the parameters will cause large error in design; 3. Unreasonable grouting may manually increase the rock pressure on the top of arch; 4.There will be a certain thermal stress in the lining during operation,but the stress is not great, being only about one tenth of the allowable tensile stress of the reinforcing bars.

本文通过断层地区的一个引水压力隧洞的设计、施工和运行观测,说明了以下几个问题:1.设计断层区的隧洞衬砌时,应考虑一部分外水压力以抵消部分内水压力;2.设计中合理选定岩石的力学参数非常重要。这些参数如选择不当,将使设计发生错误;3.不合理的灌浆可能人为地增加顶拱山岩压力;4,隧洞衬砌运行时具有一定的温度应力,但其值不大,仅为钢筋允许拉应力的十分之一左右。

Focussed on the study of soft nitriding of the rotor in a high pressure hydraulic motor consigned by Wuhan Marine Machinery Plant,an investi- gation involving the comparison between different soft nitriding processes and soft nitriding media is made.Based on the findings acquired,the study is stressed on the influence of the composition of the ionic soft nitriding gaseous mixture CO_2+NH_3,the pressure and temperature condi- tions within the nitriding furnace,on the rate of growth of the case depth of the 42CrMo workpiece,the metallographic phase composition of the hardened case and its wear resistant behavior.It is believed that the recom- mended process described in this article surpasses conventional gaseous soft nitriding processes in many ways.

本文针对武汉船用机械厂高压油马达转子软氮化问题,在对比了不同软氮化介质和方法的基础上,重点研究了 Co_2+NH_3离子软氮化气氛比例、炉内压力、渗氮温度对42CrMo 钢渗层形成速度、化合物层相组成、耐磨损性的影响,认为此法优于一般气体软氮化和其它离子软氮化法。
