摘　　要：为了解决目前评价方法复杂、不便在现场使用的现状,提出了一种以图形表示为主的快速评价法,该评价法主要分为两个步骤执行。第一步为根据评价指标体系确定指标的权重,并进行排序,以选择第二步绘图时绘制的指标。它是评价的准备阶段,是根据专家的意见或计算在场外确定的。第二步在指标权重排序中选择前若干指标并在现场确定他们的惩罚值,针对几个备选方案进行绘图,并根据图解准则分析。最终得到最具影响性的几个指标和惩罚值最小的最优方案。这里权重的确定使用模糊AHP法。使用矿山法、新奥法、掘进机法和盾构法作为备选方案,通过快速图解法在现场确定具体的施工方式,结果表明:对于举例隧道工程而言,盾构法的各指标惩罚值最小,对于这个隧道工程是较适合的施工方式。新奥法和掘进机法对于这个工程的适应性差不多,矿山法是最不适合的。In order to solve the present situation that the current assessment method is complex and inconvenience to use, a rapid graphical assessment method was given with graphical representation. The assessment method was mainly divided into two steps. In the first step, the index weights were determined based on assessment index system and sorted, to select the index of plotting drawing in the second step. As the preparation stage of the assessment, it was determined according to the opinions of the experts or calculation out of construction site. In the second step, the indexes in front of the index weight sorted were selected, and their punishment value were determine in the construction site, with that and several alternatives scheme, a rapid assessment figure was drawn, and graphic analysis was conducted according to the graphic guidelines. Finally the most influential several indexes and minimum punishment value of the optimal solution were obtained. The weighs were determined using fuzzy AHP method. Using mining method, new Austrian method, boring machine and shield method as an alternative of construction schemes, the specific way of construction was determined through rapid graphical method in the field. The re- suits showed that for the example of tunnel engineering, the punishment value of shield method is the minimum val- ue, which is suitable for the construction of this tunnel engineering. New Austrian method and machine method had similar adaptability for this construction, and mining method was not appropriate.
