【摘要】：近年来,伴随着全国各沿海城市经济的高速发展,许多港口工程、围堰和滨海新区开始建设,土地资源已经成为制约其可持续发展的关键因素。因此,开发利用滩涂资源和发展海洋经济的首要工程即利用沿海滩涂进行围海造地工程,以缓解经济快速发展和土地资源的相对匾乏之间的矛盾。 目前填海造地的方法有很多,其中由于在经济性及其快速性方面的优势,吹填法已经成为有效且应用广泛的技术。但是为了尽快的进行基础设施建设,以满足招商引资等需求,吹填造陆到工程建设的周期越来越短。因此围海造地后吹填土的地基处理方法必须适应目前严峻的形势,不仅时间紧迫,同时又面临着所需处理土体为淤泥、淤泥质土等软弱土,砂土运输的难度大、成本高、大型机械无法进场等不利情况。 本文是在前人研究工作的基础上,结合各吹填型围海造地建筑地基加固的工程实例,主要进行了以下的工作： (1)总结并对比了目前适用于吹填型围海造地建筑地基加固方法和各方法的适用条件。 (2)分析研究围海造地建筑地基处理实例,并总结各案例成功与失败经验。 (3)对吹填型围海造地建筑地基加固进行比较研究。 (4)对将来围海造地建筑地基处理方法进行探讨。
[Abstract]:In recent years, with the rapid economic development of coastal cities in China, many port projects, cofferdams and new coastal areas began to be built, and land resources have become a key factor restricting their sustainable development. Therefore, the first project of exploiting and utilizing the resources of the tidal flat and developing the marine economy is to use the coastal tidal flat for the reclamation of the sea, in order to alleviate the contradiction between the rapid economic development and the relative shortage of the land resources. At present, there are many methods of land reclamation, among which, because of its advantages in economy and rapidity, blow filling has become an effective and widely used technology. But in order to carry on the infrastructure construction as soon as possible in order to meet the demand of attracting investment and so on, the period from filling land to engineering construction is getting shorter and shorter. Therefore, the foundation treatment method of filling soil after reclamation must adapt to the severe situation at present. It is not only urgent in time, but also faced with the need to deal with soft soil such as silt, silt soil and other soft soil, so the transportation of sand is difficult and high cost. Large machinery can not enter the field and other adverse conditions. This paper is based on the previous research work, combined with the engineering examples of each type of reclamation construction foundation reinforcement. The main works are as follows: (1) summarizing and comparing the current methods and conditions of foundation reinforcement for reclamation buildings. (2) analyzing and studying the examples of foundation treatment of reclaimed land buildings. The successful and failed experiences of each case are summarized. (3) the comparative study on the foundation reinforcement of the reclaimed land building is carried out. (4) the treatment method of the foundation of the land reclamation building in the future is discussed.
