摘要
通过西南地区机场工程地质特征的分析,研究了该地区影响机场建设的主要工程地质问题:边坡和地基的稳定性、地基的变形问题等,并指出了它们的危害性,还通过机场的工程实践,提出了上述问题的处理方法。机场建设包括场道、隧道、供油、排水和建筑工程等。机场的特点是场地面积大、分布广,跨越的地质和工程地质单元多,涉及的工程地质问题也最多(如边坡稳定性、软土、膨胀土、岩溶、季节性冻土、地下水等问题),而西南地区为全国机场工程地质问题最多,且工程地质条件最复杂的地区,机场建设与其工程相比,有不同的要求和特点。机场属国家重大工程,工程量大,投资巨大。因此,加强对区内工程地质条件的研究,寻求科学、合理、有效的防治措施,具有重要的现实意义。
The engineering geological problems of the airport buildings is studied through analysis of specific property of engineering geology in the airport of southwest China. They include the steadiness of the landslide and the foundation, the deformed problem of the foundation and so on. The perilousness is pointed out, and the treatment method of the aforementioned problems is put forward.The airport building may contain the airport runway engineering, the tunnel engineering, the fuel feed engineering, the drainage work and the architectural engineering and so on. The charactristics of the airport has big area, architectural distribution wide, several units of the geology and engineering geology leap over and many engineering geological problems touch upon(such as, landslide steadiness, soft soil, expansion soil, karst, seasonal frozen soil and groundwater problems and so on). South-west China is the most complicated area of the engineering geology problems. Compared with other engineering building the airport building has different and characteristics. The airport building is a major engineering in China. Therefore, to research the conditions of the engineering geology and to explore effective prevention and treatment measure is of practical significance.
