How to ascertain the sliding surface and the factor of safety(FS) is the key problem of slope stability.The failure model of a slope is supposed at first and then the sliding surface and the factor of safety are computed approximately during analyzing the slope stability all over the world.However,the hypothesis cannot reflect the real state of slope sliding.In this paper,the critical failure surface with the lowest value of FS is computed and the better result is got by means of GA.  相似文献

To research role of biomedical engineering in treatment of Gram_negative bacterial sepsis,and chemical configuration of endotoxin and role of endotoxin in septic shock and multiple organ failures were analyzed.Effects of various biotechnology in treatment sepsis were compared. There are relationship between in endotoxin and sepsis,no effective medication for sepsis. Hemoperfusion with Polymyxin B immobilized absorbents could remove endotoxin of blood, decrease flammatory mediators(eg,tumor necrosis factor-alpha and interleukin-1) of blood ,and improve hemorheology. Polymyxin B immobilized absorbents are important in treatment patient of sepsis by its specific absorbing endotoxin .  相似文献

This article states systematically the fundamental conception of the mode of construction management general contract, the contract structure and the organization structure through the analysis of the construction characteristics of Shanghai large-scale projects, considering the situation of China and the characteristics of this line. It also summarizes the characteristics of the mode of construction management general contract through the example of the Pudong International Airport Construction. The mode of construction management general contract not only meets the needs of construction technique in bettering the design of construction project building, but also releases the pressure in middle and later management of construction project building and overcomes the deficiency of the long-term building period, hard-to-control investigation brought by the problem of design, purchase, construction divided from and restricted by each other existed in the traditional contract mode. It also helps the contractor to provide socialized, specialized, commoditized service for the contractor. Helps to overall arrangement, economized investment, management level improve ment can be given. So it has the superiority in super large-scale projects construction compared with the traditional construction management.  相似文献

The flow characteristics of multi-jes in the same direction and in great velocitydifference in combustion chamber were researched by the cold mould simulating test of self-designedlow- calorie value gas burner.The results showed that the large negative pressure region and back-flow region would be produced by the multi-annular jets with high-velocity air involve intensivelythe central low-velocity gas jet and by virtue of the small main air volume resulting by some extentcirculation of gas jet.These have the advantage of realising homogeneously mixing between air jetsand gas jet and combusting steadily.  相似文献

On the base of the logic flow chart of the building construction's material request plan,the three prerequisites are given for MRP being introduced into building construction:the construction item's project schedule,the listing of the materials that will be used in the construction item and the information of the current stock in the construction unit must be gained. The prerequisites are also solved: the construction item's project schedule is made through network planning technology and database's programming; the listing of the materials is memorized according to the construction act; the up_to_date storage information can be gained by contacting to the storehouse's management department in time. Finally, the material request plan is drafted by the method of MRP.  相似文献
