（山西省民用建筑設(shè)計研究院 太原 030012）[提要] 結(jié)合工程實例，詳細介紹了低強度等級混凝土樁與振密砂石樁的組合型復(fù)合地基。試驗研究及理論計算表明，該復(fù)合地基能充分發(fā)揮兩種樁的特點，提高地基承載力，經(jīng)濟效益顯著。
[關(guān)鍵詞] 混凝土樁 振密砂石樁 組合型復(fù)合地基Based on practices, the composite foundation with low grade concrete piles and vibro-casting sand-gravel piles is introduced. Experiments and calculation show this kind of base can improve ground bearing capacity and the economic benefit is good.
