一、前言在港口工程中,地基基础的建筑费用在总建筑费中占很大比重。特别是海港工程,一方面施工条件较差(风大、浪高、水深或大多数情况下为超软地基),又受到海水冲刷或腐蚀的影响;另一方面,多数远离砂石原料产地,受原材料供应和运输方面的限制。因此,选择工程性能好,价格低廉,施工方便的建筑材料是降低工程造价的有效办法。这种材料之一,就是目前在国外已大量采 I. Introduction In the port project, the cost of building a foundation is a large proportion of the total construction cost. In particular, the harbor project, on the one hand, has poor construction conditions (windy, wave height, water depth or in most cases ultra-soft foundations) and is also affected by seawater erosion or erosion; on the other hand, Limited by raw material supply and transportation. Therefore, the choice of engineering performance, low prices, convenient construction materials is an effective way to reduce construction costs. One of such materials is that it has been massively collected abroad
