项目摘要
Now land reclamation is carried out in Japan, but slope stabilization on the decomposed granite soils area causes problems during land conservation.The design of land reclamation can't be practiced in the same pattern, for the decomposed granite soils are unstable on action of water, weathering, and also components of its minerals differ from region to region.Tests were carried out on the decomposed granite soils sampled from some lands under reclamation to propose elementary data which can be considered for the suitable method of reclamation for each region. We studied their scientific and engineering properties in accordance to various weathering degrees.Consequently, their scientific and engineering properties such as soil grading, shear strength and permeability are influenced and changed with mineral components and weathering degrees. In addition, shear strength deteriorate with moisture content. Accordingly, the method of drainage is the most important factor on reclamation of the decomposed granite soil area. Namely, as the decomposed granite soils are easily broken and eroded by water action, drainage must be done fast and safely by water erosion protection and farming. We suggested the investigating point of construction countermeasure for drainage of spring water to foundation stability and design of drainage system. Furthermore we proposed new beneficial method of disaster prevention combination which are decided with a use of a point table in order to design land reclamation and conservation.The important problem to be solved, is the planning to take measure of drainage and embankment for respective areas, and we think that results of this study hold new point of view and can contribute to land reclamation and conservation for decomposed granite soil areas scientifically and technically.
日本目前正在进行土地复垦,但在花岗岩风化土地区进行边坡加固是土地保护中的一个难题,由于花岗岩风化土在水、风化作用下不稳定,不同地区花岗岩风化土的矿物组成也不同。填海,以提出基本数据,这些数据可以被认为是每个地区的适当填海方法。根据不同的风化程度,研究了其科学工程性质,结果表明,土的级配、抗剪强度和渗透性等科学工程性质受矿物成分和风化程度的影响和改变。此外,剪切强度随含水量而变差。因此,排水方法是风化花岗岩土壤区复垦的最重要因素。也就是说,由于风化的花岗岩土壤很容易被水的作用破坏和侵蚀,必须通过防止水蚀和耕作来快速安全地排水。提出了泉水排水施工对策对地基稳定性和排水系统设计的研究重点。提出了利用点表确定防灾组合的新方法,为土地复垦与保护设计提供了依据,重点解决的问题是分区排水与堤防措施的规划,研究结果为花岗岩风化土的复垦和保护提供了新的思路和方法科学和技术上。
