河谷下切 meaning in Chinese
valley trenching
Examples
- The mechanical genesis of the complicated rock mass is because several times of tectonism in pro - period made the structure of rock mass in the right dam foundation damaged seriously and rock mass alteration made its mechanical character more anisotropy . after that the fractures in the right dam foundation slope were stretched at the beginning of the quaternary period because in the period yakouhoushan mountain quaquaversal dome was blowups quickly . at the same time , the valley trenching of lancang river reach to 800 - 1000 meter in altitude at the right bank in nuozadu dam site
导致右岸岩体复杂化的成因是，右岸岩体在早期遭受了多期构造作用和岩体蚀变的基础上，第四纪早期丫口后山穹隆的快速隆起与当时河谷下切至800m 1000m高程这一特殊因素组合引起了右岸岩体沿原有的断裂(裂隙)张开，使地下水等风化营力能够到达坡体较深部位，经过长期的风化卸荷作用，形成了右岸复杂岩体。 - In the last part of the thesis a study of engineering effect about the complicated rock mass was done base on a numerical simulation and the engineering geological condition in the dam site . numerical simulation result reflect several disciplinarian of stress - distortion action in the right bank slope . firstly , today ' s right bank stress field mainly is grave stress field
在上述研究工作的基础上，通过对右岸岩体应力?形变作用的有限元数值模拟分析，表明：右岸坝基岩体的现今应力场主要是在自重应力场的基础上，河谷下切应力、分异的应力场。
