摘　　要：多指标评价砂土地基加固效果的方法通过分析各指标的深层含义,建立各指标之间的相互联系,避免了依赖单一指标的片面性和随机性,更加全面、客观、有效地评价地基加固效果,能形成体系,各个指标之间相互联系,互相验证,同时使验收指标目的更加明确,从而更好地对地基效果进行评价。The method of assessment for the improvement of dynamic compaction sandy ground based on multiple indexes is that by analyzing the deep meaning of every index the relationship between the indexes was established so that one-sidedness and randomness which is dependent on a single index can be avoided and it is more comprehensive, objective and can evaluate the effect of ground improvement more effectively. The various indexes are connected and proved each other so this method are systematized. At the same time, the method makes the purpose for the test indexes more clearly so that the better evaluation for the effect of ground improvement can be realized.
