公路系统地勘现状分析

公路工程地质勘察和一般工民建相比，具有显著的行业特点，体现在线路长，穿越的工程地质单元较多，工点多，勘察手段多。另外，既要把握全线路地质情况，又要有重点突出，如高陡边坡和特大桥桥址区等工点为勘察工作的重点。随着地勘的无序市场化，公路勘察质量也引人担忧，本文通过整理参与的工程项目，分析其问题，指出勘察和设计脱节依然是客观存在的，是影响勘察成果的最主要因素之一。此外，甲方或设计院一味的压缩克扣勘察费用，难以发挥勘察工程师的才智，也不利于勘察设计水平的提高，甚至造成工程事故； 勘察单位一味地迎合市场，轻视勘察质量，同样不利于自身行业的健康长远发展。

STATUS ANALYSIS OF HIGHWAY ENGINEERING INVESTIGATION

Compared with general civil engineering investigation, highway engineering geological investigation has its own significant feature-longer line, more engineering geological units, more construction sites, more survey methods. To ensure the survey quality, we have to control the whole line geological condition. Meanwhile, we also have to regard conditions such as high and steep slope, special span bridge and so on. However, geological investigation marketization is developing without general standard, which affects the investigation quality and development. Based on highway project and investigation report, this article points out that geological survey and engineering design are not relevant enough as the highway project needs, which affects the investigation and design result most. Because owners and design companies always suppress design fee, which prevents the investigation engineers to accomplish their inspiration, then limits the design level. More importantly, it may lead engineering accidents. In order to cater to the market, companies have to pay more attention on contract amount than investigation quality, which is another negative factor that will prevent the benign development of investigation industry.
