1、解讀人工挖孔樁技術(shù)在工程中的運(yùn)用中英文現(xiàn)代社會(huì)城市化進(jìn)程的不斷加快,各類民用與工業(yè)修建項(xiàng)目也日益添加。在每項(xiàng)修建工程中,都需求對(duì)修建質(zhì)量和布局安全進(jìn)行嚴(yán)厲控制,尤其是關(guān)于修建根底的處置需求更高。人工挖孔樁施工技能比擬便利,施工速度較快,且不需求運(yùn)用大型的機(jī)械設(shè)備,對(duì)其它修建物的擾動(dòng)影響也較小。一起,人工挖孔樁還能節(jié)約很多的施工本錢,其抗震才能要比木樁、混凝土打入樁強(qiáng),因而在工民建工程中得到了十分廣泛的運(yùn)用。Acceleratingtheurbanizationprocessinmodernsociety,allkindsofcivilandindustrialconst
