新疆某工程碾压式沥青混凝土心墙坝设计

Design of A Rolling Asphalt Concrete Core Dam for A Project in Xinjiang

新疆某水利枢纽工程坝址区主要分布第四系下更新统西域组西域砾岩及第四系堆积物,西域砾岩属软岩且遇水易软化,工程设防烈度为Ⅷ度。针对该坝址地震烈度高、地质条件差等特点,结合“水利工程补短板、水利行业强监管”的行业形势,主要介绍了碾压式沥青混凝土心墙坝土料设计、防渗体设计、渗流计算、稳定计算和沉降及应力应变变形计算等关键技术的设计经验和成果,可为建设条件类似的工程提供借鉴。

The dam site area of a water conservancy project in Xinjiang is mainly distributed with Quaternary Lower Pleistocene Western Formation Western Conglomerate and Quaternary Deposits.The Western Conglomerate is soft rock and is easy to soften when exposed to water.The engineering fortification intensity isⅧ.In view of the high seismic intensity and poor geological conditions of the dam site,combined with the industry situation of"compensating for shortcomings in water conservancy projects and strong supervision of the water conservancy industry",this paper mainly introduces the design of the soil material,the design of the anti-seepage body,seepage calculation,stability calculation,settlement and stress-strain-deformation calculation of the roller compacted asphalt concrete core dam.The design experience and results can provide reference for projects with similar construction conditions.
