近几年随着城市化、工业化进程加快,城市工程建设迅猛发展,引起或诱发的环境岩土工程问题愈来愈严重,其中工业企业对地基土污染问题就是较为严重的环境岩土工程问题。所谓污染土,主要是指普通地基土受到工业生产过程中产生的三废侵蚀,而使土质发生化学变化,改变了土的原有性状的一类土。在工程中,污染土可以引起地基强度降低,导致建筑物失稳或破坏,引发一系列工程质量事故,因此研究污染土的污染机理、性状和因地制宜采取整治措施对稳定建设工程质量,保护环境具有重要意义。
In recent years, with the process of urbanization and industrialization being speeded up, the construction of urban engineering is developing rapidly, and the environmental geotechnical engineering problems caused or induced are getting more and more serious. The pollution of the foundation soil by industrial enterprises is a serious environmental geotechnical problem. The so-called contaminated soil, mainly refers to the common base soil by industrial waste generated during the three erosions, and make the soil chemical changes, changing the original characteristics of a class of soil. In the project, the contaminated soil can cause the foundation to reduce its strength and lead to the instability or destruction of the building, causing a series of engineering quality accidents. Therefore, it is necessary to study the pollution mechanism and characteristics of contaminated soil and take remedial measures according to local conditions to stabilize the construction quality and protect the environment Significance.
