摘要
类刚性-大直径水泥土(旋搅)桩是水泥土桩系列中的一种新桩型,其特有的有关造桩的科技成果已获得了众多工程专家的赞誉和社会的公认,并已在珠江三角洲地区推广应用。其中,最具持续发展意义的成果,则是可促进建筑工程实现低碳目标:即低耗、低噪、无污染施工。通过该桩型的一些实例,结合珠三角地区的地层特点,重点介绍了在含水量为70%-80%的(欠固结)淤泥地层中,Φ1000-1200 mm水泥土桩现场抽芯桩身强度95%达到qu(28d)≥1.5-2.0 MPa的成果,以及"Φ1000 mm水泥土桩穿透N≥38击粗(砾)砂层"的成果。
The rigid-like and large diameter cement-soil mixing pile is a new pile type in cement-soil mixing pile series;its unique scientific and technological achievements have won the praise of many engineering experts and it was popularized and applied in the Pearl River Delta region with most significant outcome of sustainable development of low-carbon goal: low consumption,low noise and no pollution construction.By the examples of pile type and combining with the geological features of the Pearl River Delta region,the paper introduced that in the pile-site,the pile core-pulling strength of 95% 1000-1200 mm cement mixing piles reached to qu(28d)≥1.5-2.0 MPa in water content of 70%- 80%(due to consolidation) of sludge formation,and 1000 cement-soil mixing pile penetrated through N≥38 hit rough(gravel) sand formation.
