公路工程建设中的岩土工程问题

公路工程建设呈现的岩土工程问题主要有地基稳定问题、边坡稳定问题、围岩稳定问题和渗透稳定问题。这些问题对工程的影响体现在变形和强度两个方面，根据工程的功能和性质，应考虑按变形控制或强度控制来确定工程安全标准和评价工程稳定性。基于岩土工程问题的产生条件，提出了在工程实践中应注重的内容及研究方向，如：路基岩土的强度与变形特性研究、地基处理技术及工程特性研究、深基础与地基相互作用研究、边坡稳定性评价方法研究、边坡治理技术及可靠性研究、围岩与结构应力变形研究、地下水对各种岩土体的作用研究等等。

Geotechnical Engineering Problems in Highway Construction

Main geotechnical engineering problems in highway construction have stabilities of foundation, slope, surrounding rock and permeable. Influences of these problems on engineering have reflected on two aspects of deformation and strength. According to engineering function and property, in determination of engineering safety standards and stability assessment, deformation control or strength control should be considered. Based on conditions of geotechnical engineering problems come into being, brought forward matters should be paid attention to and investigating orientation in engineering practices, such as： studies on roadbed rock and soil strength and deformation characters, foundation processing technologies and engineering properties, interaction of deep foundation and groundsill, slope stability assessment methods, slope governing techniques and reliability, surrounding rock and structure stress deformation and groundwater influences on various rock and soil masses etc.
