分析CFG桩体施工的影响为工程应用提供一定的借鉴。桩间土在桩体施工完成后,随着龄期的增长,强度先减小后增大,最终强度明显提高;桩间土的含水量在施工后有显著下降,幅度可达10%到50%,这说明刚施工完的桩体起到了很好的排水作用;粉煤灰明显提高了桩体的前期强度,每100kg混凝土中掺入3kg粉煤灰较为经济。
分析CFG樁體施工的影響為工程應用提供一定的藉鑒。樁間土在樁體施工完成後,隨著齡期的增長,彊度先減小後增大,最終彊度明顯提高;樁間土的含水量在施工後有顯著下降,幅度可達10%到50%,這說明剛施工完的樁體起到瞭很好的排水作用;粉煤灰明顯提高瞭樁體的前期彊度,每100kg混凝土中摻入3kg粉煤灰較為經濟。

The analysis of the effect of CFG pile construction can provide certain reference for engineering applica?tion. As the growth of the age,The strength of Soil between piles increase with the decrease of the first and the ulti?mate strength increased significantly after the pile construction is completed;The water content of soil between piles in construction has dropped significantly,the range of 10%to 50%,suggesting that the pile had just finished the construction has played a very good drainage effect;The early strength of pile is increased obviously by fly ash and it is more economic to put 3 kg of fly ash in per 100 kg concrete.
