环境工程英文文献附带带翻译：地铁开挖引起的环境问题及补救建议 Environmentalproblems caused by Istanbul subway excavation and suggestions for remediation Ibrahim Ocak Abstract: Many environmental problems caused by subway excavations have inevitably become an important point in city life. These problems can be categorized as transporting and stocking of excavated material, traf?c jams, noise, vibrations, piles of dust mud and lack of supplies. Although these problems cause many dif?culties, the most pressing for a big city like Istanbul is excavation, since other listed dif?culties result from it. Moreover, these problems are environmentally andregionally restricted to the period over which construction projects are underway and disappear when construction is ?nished. Currently, in Istanbul, there are nine subway construction projects in operation, covering approximately 73 km in length; over 200 km to be constructed in the near future. The amount of material excavated from ongoing construction projects covers approximately 12 million m3. In this study, problems?primarily, the problem with excavation waste EW?caused by subway excavation are analyzed and suggestions for remediation are offered. Keywords: Environmental problemsSubway excavationWaste management Introduction Nowadays, cities are spreading over larger areas with increasing demand on extending transport facilities. Thus, all over the world, especially in cities where the population exceeds 300,000?400,000 people, railway-based means of transportation is being accepted as the ultimate solution. Therefore, large investments in subway andlight rail construction are required. The construction of stated systems requires surface excavations, cut and cover tunnel excavations, bored tunnel excavations, redirection of infrastructures and tunnel construction projects. These elements disturb the environment and affect everyday life of citizens in terms of running water, natural gas, sewer systems and telephone lines. On
