1 影响公路工程造价的动态因素1.1 工程设计的变化任何一个建设项目,都是从确定设计任务书、进行初步设计、技术设计、施工图设计、施工、以至竣工验收的具体操作中,从初识到认识,再从认识到实践,由粗到细、由浅至深逐步深化的过程。由于种种影响工程设计的客观条件和主观因素的变化,因而在公路工程建设过程中,工程设计的变更是客观存在的,这主要是由于工程设计的水平和某些不可预见等因素所导致的,如设计线字程的变化、设计线线位的变更、桥涵位置与实际不符的变更、软土地基处理的变更等等。这些动态因素均能直接造成工程造价的增减,其数值是不可忽视的。
1 Dynamic Factors Affecting the Cost of Highway Engineering 1.1 Changes in Engineering Design Any construction project starts from identifying the design task book, carrying out the preliminary design, technical design, construction drawing design, construction, and final acceptance. To recognize, and then from the realization of practice, from coarse to fine, gradually deepening the process from shallow to deep. Due to the variety of objective conditions and subjective factors that affect the engineering design, engineering design changes objectively in the process of highway construction. This is mainly due to the engineering design level and some unforeseeable factors, Such as the design line word changes, changes in the design line position, bridge and culvert changes in the actual discrepancies, soft ground changes and so on. These dynamic factors can directly increase or decrease the project cost, the value can not be ignored.
