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.
