本文简略地介绍近年来在港澳地区高层建筑较多采用的井管浇注混凝土柱基础,港澳通常称为沉箱基础,即采用逐段开挖浇筑井管,待达到岩层后再浇注混凝土建成柱基础的一种方法。 港澳地区近年来的建筑,都向高层发展,一般公寓住宅都在15层以上,办公大楼、商业大厦发展至40～50层。港澳地势靠山临海,市内可供建筑用地极少,城市高速发展,促使填海造地,开挖山坡要地,在市内则只能拆旧房建新楼。港澳处于沿海多山地区,地势高低起伏较大,基岩埋深离地面几米至30～50
This article briefly introduces the well-pipe concrete column foundations that have been used in high-rise buildings in Hong Kong and Macau in recent years. Hong Kong and Macao usually call caisson foundations, ie, use segment-by-section excavation cast-in-place well pipes, and wait until the rock formations have been poured before pouring concrete built-up columns. a way. In recent years, the buildings in Hong Kong and Macau have all developed toward high levels. Generally, apartment buildings are more than 15 floors, and office buildings and commercial buildings have been developed to 40 to 50 floors. Hong Kong and Macao are backed by the sea, and there are few construction sites available in the city. The rapid development of the city promotes land reclamation and land excavation. In the city, only new buildings can be demolished. Hong Kong and Macao are in the coastal and mountainous regions, and the terrain fluctuates greatly. The bedrock is buried several meters from the ground to 30-50.
