摘要
《建筑边坡支护技术规范》(GB 50330-2013)提出了有无外倾结构面及结构面软硬不同情况下侧向岩石压力计算公式,其计算公式复杂,计算原理与概念不简明,实际应用中容易概念不清出现错误。基于边坡极限平衡原理对岩石边坡的侧向岩石压力计算体系优化,提出了新的边坡侧向岩石压力求解思路,并经算例验证了体系优化的可行性与简易性。
Technical Code for Building Slope Engineering(GB50330 —2013) proposes the formula for calculating lateral rock pressure with or without out-dip structural plane and different hardness of the structural plane. The calculation formula is complex, the calculation principle and concept are not simple, and the concept is easy to be unclear and even wrong in practical application. The lateral rock pressure calculation system of rock slope is optimiazed based on the limit equilibrium principle of slope. A new way of calculating lateral rock pressure of slope is proposed, the feasibility and simplicity of the system optimization is verified by the example.
