［摘要］寧波地區(qū)地質(zhì)軟弱，由于場(chǎng)地土沉陷無法避免，引起墻面開裂及地坪不均勻沉降，工程完工后業(yè)主仍需要定期保養(yǎng)、修護(hù)。因此，在工程設(shè)計(jì)初期應(yīng)預(yù)先考慮對(duì)策，減小不均勻沉降帶來的危害。針對(duì)寧波工業(yè)廠區(qū)典型建筑物、構(gòu)筑物基礎(chǔ)和地坪特性，提出如下對(duì)策：1）對(duì)載重較大或設(shè)備有精度要求的建筑物，優(yōu)先采用筏板基礎(chǔ)及樁基礎(chǔ)，其次選擇地質(zhì)改良；2）大型儲(chǔ)罐基礎(chǔ)優(yōu)先采用樁基礎(chǔ)，中小儲(chǔ)罐基礎(chǔ)宜選用環(huán)梁基礎(chǔ)；3）對(duì)內(nèi)部倉儲(chǔ)及運(yùn)輸有嚴(yán)格要求的大型倉庫優(yōu)先采用樁基礎(chǔ)；4）對(duì)中央控制室地坪，即有美觀及操作要求，又不易于修補(bǔ)者，宜采用樁基礎(chǔ)及結(jié)構(gòu)地坪。

Abstract: The crack of wall and different settlement of ground floor for buildings and structures is inevitable due to the subsidence and deformation of the soft soil stratum in Ningbo. Owners still have to regular maintain and repair after project completion. Therefore, the countermeasures should be taken into account in advance at the beginning of design, to reduce the damage done by the different settlement. For the characteristic of foundation or pavement of typical industrial factory buildings, structures and site soil, the countermeasures were pointed out as below: 1) For building having heavy loading or having high request of equipment precision, mat foundation or pile foundation shall be highly preferable to soil improvement; 2) For large tank, pile foundation is a prior selection; for medium and small tank，circle beam foundation is better； 3)For large warehouse with high request of storage and transportation, pile foundation is a prior selection; 4)For central control room with both beautiful and operational requirements, and difficult to repair, piling foundation and structural floor shall be better.

Keywords: industrial building; soil improvement; foundation selection; uplift pile; different settlement
