بررسي رفتار بدنه سد مارون با استفاده از نتايج شبكه‌ي ابزار دقيق در دوران ساخت و آب‌گيري

Evaluation of Marun Dam Behavior During the Construction and Operation Period Using Instrumentation

در مقاله‌ي حاضر، نتايج و قرايت‌هاي دستگاه‌هاي رفتارنگاري نصب شده در هسته‌ي سد، بررسي و تفسير شده و براساس اين نتايج رفتار بدنه سد درحين عمليات ساخت و هم‌چنين در دوران آب‌گيري و بهره‌برداري كنترل و ارزيابي شده است. اين مطالعه از سه بخش عمده شامل ارزيابي وضعيت فشار آب‌ها، تنش‌هاي درون هسته و بررسي نشست‌ها و تغيير شكل‌هاي آن تشكيل شده است.

Marun dam with a height of 170m is one of the largest embankment dams in Iran. The dam is a zoned rockfill dam with a central clay core. Due to the importance of safety and stability control of the dam body, a complete monitoring network including different instrumentation systems, has been designed and installed in the dam body. In this paper, the data obtained from the instruments, installed in the clay core, were processed and interpreted. Based on the outcomes, the behavior of the dam body during the construction in the impounding stage and operation period was evaluated and discussed. This study consists of three major parts including: the pore pressure distributions, stress states conditions in the clay core and evaluation of its settlements and deformations in the dam body.
