盾构机的集中润滑

盾构机中的集中润滑是作用于盾构机的关键部位刀盘驱动大轴承、唇口密封等。刀盘驱动大轴承润滑不良，会带来大轴承的咬死，造成刀盘不能工作，影响盾构使用；唇口密封润滑不好和压力过低；会造成唇口密封摩擦阻力增大，磨损增加，缩短使用寿命，润滑油压力过低，会造成盾构机外部的泥沙进入唇口密封，损坏唇口密封，进一步进入刀盘轴承，引起轴承咬死，会使盾构无法掘进，所以盾构机中的集中润滑是一个非常重要的位置，同时，盾构机中的集中润滑是强制性的润滑。

Kink in the intermodal supply chain: interorganizational relations in the port economy

The intermodal logistics supply chain is designed to move goods from the point of production to the point of consumption as quickly and as cheaply as possible. The ability to accomplish this objective has allowed for the wholesale geographic relocation and offshoring of basic manufacturing and assembly. As a chain of linked and integrated organizations characterized by sequential interdependence, interorganizational relations play a key role in determining the level of integration and seamlessness. Yet there is one critical interorganizational link in the chain that deviates from this vision. This is the relationship between the shipping container terminal and drayage trucking operations which is better described as a form of intermodal disintegration. The weakness in this link of the supply chain is explained by the divergent industrial structures and labor market conditions, the unique nature of the transaction, and the externalization of costs to subordinate workers.

Problems of the carless in the United Kingdom and the United States

An examination of current population statistics shows that in the U.S. more than half of the population is without immediate access to a car, and in the U.K. more than three-fifths of the population is without access to a car. This phenomenon has been accentuated by national investment in both countries in major highway programs. The term carless refers to more than just households that own no cars. It extends, in households with cars to those without licenses (old and young), the handicapped, and even the licensed drivers who have no access to the family car when it is in use elsewhere (e.g. at work). The most severely effected are those in urban areas and especially the urban poor. Transportation expenses are limited for the poor when other family expenditures (food, shelter) take a high priority. Once the work trip has been satisfied, money for other trips, for the poor, is not always available. One solution to cost-free travel is pedestrianism (walking), but this too is difficult in urban areas where the pedestrian has been overlooked in favor of the car. Solutions to problems of the carless include dial-a-ride, better public transit, and better design of urban form.     

A test of the two-mode UMOT in the Netherlands

The UMOT model, presented as an alternative to conventional travel demand models, is critically examined for its feasibility to predict vehicle distance travelled and average daily traffic in The Netherlands. Using data from the National Travel Survey (OVG) 1978 a Dutch version of UMOT is developed, and an attempt is made to validate it on historical data from the period 1960 to 1980. Some comparisons are made with results of similar work using 1976 survey data in the UK by the Transport and Road Research Laboratory.     

挤压性地层中隧道围岩变形控制

从穿越瑞士列奇堡隧道的挤压变形性极强的碳质页岩带的经验中,可以得出下述结论：圆形含承压单元的支护截面,其收敛变形性总趋势要比马蹄形不含承压单元的支护截面小；圆形支护截面与马蹄形支护截面的变形性没有本质的区别；由于山体构造的不均一性,导致开挖断面的不规则变形,这是使承压单元过早脱落的原因。     

The influence of built environment to the trends in commuting journeys in the Netherlands

In this paper we describe commuting trends in the Netherlands in the past decade and examine the influence of urban form and travel accessibility on commuting journeys over time on the basis of data from the Dutch National Travel Survey. Exploratory analysis is performed to identify changes in commuting participation, departure time, commuting time, commuting distance and the modal split. Regression analysis and choice models are used to examine the influence of the built environment on commuting parameters over time. The results indicate that urban form has consistently influenced the parameters of commuting journey in the Netherlands in the last 10 years. However, the trend of the influence is unique for each commuting model. Some influences have become less significant in the last decade and some have become stronger.
