對于獨立(li)基(ji)(ji)礎(chu)(chu)(chu)(chu)地(di)(di)(di)基(ji)(ji)處理，可按(an)變形控制進行復(fu)(fu)(fu)合(he)(he)(he)地(di)(di)(di)基(ji)(ji)設(she)計(ji)(ji)。比如，天(tian)然(ran)地(di)(di)(di)基(ji)(ji)承(cheng)載(zai)力100kPa，山西素土擠密樁施(shi)工廠(chang)家，設(she)計(ji)(ji)要(yao)(yao)求經(jing)處理后復(fu)(fu)(fu)合(he)(he)(he)地(di)(di)(di)基(ji)(ji)承(cheng)載(zai)力特征值不(bu)(bu)小(xiao)于300kPa。每個(ge)(ge)獨立(li)基(ji)(ji)礎(chu)(chu)(chu)(chu)下的承(cheng)載(zai)力相同，都是300kPa。當兩個(ge)(ge)相鄰(lin)柱荷(he)(he)載(zai)水平(ping)(ping)相差較大的獨立(li)基(ji)(ji)礎(chu)(chu)(chu)(chu)，復(fu)(fu)(fu)合(he)(he)(he)地(di)(di)(di)基(ji)(ji)承(cheng)載(zai)力相等時(shi)，荷(he)(he)載(zai)水平(ping)(ping)高的基(ji)(ji)礎(chu)(chu)(chu)(chu)面積(ji)大，影(ying)響深(shen)(shen)度深(shen)(shen)，基(ji)(ji)礎(chu)(chu)(chu)(chu)沉降(jiang)(jiang)大；荷(he)(he)載(zai)水平(ping)(ping)低(di)的基(ji)(ji)礎(chu)(chu)(chu)(chu)面積(ji)小(xiao)，影(ying)響深(shen)(shen)度淺，基(ji)(ji)礎(chu)(chu)(chu)(chu)沉降(jiang)(jiang)小(xiao)；柱間沉降(jiang)(jiang)差有可能不(bu)(bu)滿足設(she)計(ji)(ji)要(yao)(yao)求。柱荷(he)(he)載(zai)水平(ping)(ping)差異(yi)較大時(shi)應按(an)變形控制進行復(fu)(fu)(fu)合(he)(he)(he)地(di)(di)(di)基(ji)(ji)設(she)計(ji)(ji)。由于水泥粉(fen)煤灰碎(sui)石(shi)樁復(fu)(fu)(fu)合(he)(he)(he)地(di)(di)(di)基(ji)(ji)承(cheng)載(zai)力提(ti)高幅度大，柱荷(he)(he)載(zai)水平(ping)(ping)高的宜采用較高承(cheng)載(zai)力要(yao)(yao)求確定布樁參數；可以有效地(di)(di)(di)減少基(ji)(ji)礎(chu)(chu)(chu)(chu)面積(ji)、降(jiang)(jiang)低(di)造(zao)價，更重要(yao)(yao)的是基(ji)(ji)礎(chu)(chu)(chu)(chu)間沉降(jiang)(jiang)差容易控制在規范限值之(zhi)內。

成樁

灰土拌合均勻，自檢(jian)后經監理(li)工程(cheng)師檢(jian)測合格(ge)后，用(yong)小(xiao)鏟車運至現場。

樁孔回填夯實(shi)順序采用從路線(xian)中(zhong)心向兩(liang)側間隔(ge)1～2孔調(diao)填夯實(shi)。

夯錘(chui)形(xing)狀采用下(xia)端(duan)呈拋物線垂體形(xing)的梨形(xing)錘(chui)，錘(chui)重100kg，山(shan)西素(su)土擠密(mi)樁施工，夯錘(chui)直徑280mm。

每樁(zhuang)孔回填(tian)前，用(yong)錘重將孔底夯實，分層回填(tian)夯實，單次成樁(zhuang)深(shen)度易(yi)為(wei)30～40cm，填(tian)料、夯實交替進行，完(wan)成單樁(zhuang)施工。

回填時(shi)做到均勻(yun)下料，均勻(yun)夯擊，保證夯重落(luo)距(ju)及(ji)次數。

回(hui)填夯(hang)實(shi)至設計標高(gao)頂(ding)面高(gao)出10cm后，用素(su)土封頂(ding)處(chu)理。
