过湿土固化处理公路路堤试验研究

过湿土含水量过高,承载力低,难以压实和控制,无法直接用作路基填料,需要掺加固化剂进行土性改良。介绍用复合矿渣固化剂和石灰固化过湿土,其压实特性、抗压强度及CBR的试验结果:复合矿渣固化剂总体性能比石灰优越,尤其在CBR方面。

Dynamic Bayesian network based prognosis in machining processes

Condition based maintenance (CBM) is becoming more and more popular in equipment main-tenance. A prerequisite to widespread deployment of CBM technology and practice in industry is effectivediagnostics and prognostics. A dynamic Bayesian network (DBN) based prognosis method was investigated topredict the remaining useful life (RUL) for an equipment. First, a DBN based prognosis framework and specificsteps for building a DBN based prognosis model were presented. Then, the corresponding inference algorithmsfor DBN based prognosis were provided. Finally, a prognosis procedure based on particle filtering algorithmswas used to predict the RUL of drill-bits of a vertical drilling machine, which is commonly used in industrialprocess. Preliminary experimental results are promising.
