In the past over ten years, many problems, especially soft ground's non-uniform settling and large subsidence after finished and jump-off on bridge's end, arise from highway's building along national construction progresses.

近十几年来，随着国家建设的不断发展，公路建设中产生的问题，尤其是软土地基的不均匀沉降、工后沉降量大、桥头跳车等问题尤为突出，地基处理方法是否选择适当对工程的质量、工期、维修保养以及经济效益均有很重大的影响。
