The test results indicate that: 1) Compared with unmodified soils, the free swelling ratio, plastic index and clay fraction of fly ash-treated soils and Lime-treated soils decrease obviously.
Under the complex geological condition where the backfill is on thick soft clay, the design method of combining fly ash concrete pile and lime pile is presented.
针对深厚软粘土上覆新回填土的复杂地质条件，提出了粉煤灰混凝土桩与石灰桩联合进行地基处理的设计方法。
