砂土液化是高地震烈度区影响地基稳定性的重要因素之一,是引起构筑物破坏的主要形式之一。对高速公路必须进行液化地基处理,这是减轻地震灾害的根本措施。因此,如何控制和管理好处理液化地基的施工,做到既经济有效又安全可靠,对保证高速公路建成后的正常运营、减轻地震灾害具有重大现实意义。 Sand liquefaction is one of the important factors affecting the stability of the foundation in high seismic intensity areas and is one of the main forms that cause damage to structures. The liquefied foundation must be treated on the expressway, which is the fundamental measure to reduce the earthquake disaster. Therefore, how to control and manage the construction of liquefied foundation is not only economical and effective but also safe and reliable, which is of great practical significance to ensure the normal operation after the expressway is completed and to reduce the earthquake disaster.
