چکیده
در جوامع امروزی، خطوط لوله به عنوان شریان های حیاتی، برای حفظ آسایش و رضایتمندی مردم از اهمیت بسزایی برخوردار است. با توجه به روند فزاینده توسعه در ایران، لزوم احداث، بازسازی، تعمیر و نگهداری تاسیسات زیرزمینی از جمله خطوط لوله نفت، گاز، آب، فاضلاب، رواناب و ارتباطات ، جزء لاینفک عملیات عمرانی و تاسیساتی است. با در نظر گرفتن مشکلات ناشی از حفاری های روباز و گسترش تاسیسات زیرزمینی، استفاده از روشهای حفاری بدون ترانشه در صنعت ساخت رو به افزایش است تا بتواند مشکلات را اقتصادی تر و موثر تر برطرف نماید. هدف از این پژوهش شناسایی و رتبه بندی مهمترین عوامل موثر بر پذیرش تکنولوژی حفاری بدون ترانشه در ایران است. تحقیق حاضر دارای هدف کاربردی است و به روش پیمایشی و توصیفی انجام شده است. جامعه آماری این تحقیق مدیران میانی، پیمانکاران و مهندسین دستگاه نظارت و بخش طراحی شرکت آب و فاضلاب اصفهان و آب منطقه ای چهارمحال و بختیاری بوده است. در این راستا، نمونه 87 نفری به صورت تصادفی انتخاب و پرسشنامه محقق ساخت بین آنها توزیع شد و تعداد 68 پرسشنامه جمع آوری شد. بر اساس آن 8 گروه اصلی و در قالب 28 معیار فرعی به عنوان عوامل موثر بر پذیرش حفاری بدون ترانشه در ایران دسته بندی و نتایج حاصل از آن مورد تحلیل قرار گرفت. جهت رتبه بندی عوامل موثر، از آزمون فریدمن استفاده شد و از نرم افزار SPSS جهت تحلیل داده ها به تجزیه و تحلیل داده ها پرداخته شد. بر این اساس در بین 8 گروه اصلی عوامل مدیریت اجرایی، محیطی، دموگرافیک، تکنولوژی، اقتصادی، بهره وری پروژه (مدیریت ساخت)، سازمانی و فردی به ترتیب رتبه های اول تا هشتم را بدست آورده اند. همچنین در بین 28 معیار، دستگاه نظارت، ریسک ها ، محیط زیست ، بودجه، مدیر عالی اجرایی، عملکرد مکانی و جغرافیایی و هزینه های مستقیم، رتبه های برتر را به خود اختصاص داده اند.

چکیده English

In today’s society, pipelines as vital arteries play a significant role in maintaining people’s peace and satisfaction. According to growing developments in societies, the necessity of constructing, refurbishing, repairing, and maintaining underground installations such as petrol pipelines, gas, water, wastewater, runoffs, and connections is considered as the indispensable part of civil and installation operations. Regarding problems stemming from the open trench excavation methods and growth of underground installations, using trenchless technologies in the construction industry is increasing in order to solve the problems more economically and effectively. The present project aimed at recognizing and ranking the most important effective factors in accepting the trenchless technology in Iran. This research has a practical target and has been performed by the survey and the describing method. The statistical population of this research includes middle managers, contractors, and civil projects engineers of Isfahan province. In this regard, a sample of 87 people was randomly selected and the questionnaire was distributed among them. Eventually, a total of 68 questionnaires were collected with favorable consistency. This questionnaire has been designed by the investigator according to the Likert scale with high stability. Accordingly, the factors were grouped in the form of 28 criteria and 8 major groups as the effective factors on accepting the trenchless technology in Iran. Descriptive and inferential methods and the Friedman test were used to rank the effective factors, and the SPSS software was applied to analyze the data. Among the 8 major groups of executive management, environmental, demographics, technology, economically, project productivity (construction management), organizational, and individual had the first to the 8th rank, respectively. In addition, control system, risks, environment, budget, chief executive officer (CEO), special and geographical performance, and direct costs ranked the top among the 28 factors.
