研究區內子洲鎮川堡地區發育的下切河谷形成於海平面下降時期,來源於橋頭的砂質河流沉積,為疊置的、形成於三個不同三級層序底部的下切河谷充填沉積。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
導致右岸巖體復雜化的成因是,右岸巖體在早期遭受了多期構造作用和巖體蝕變的基礎上,第四紀早期丫口後山穹隆的快速隆起與當時河谷下切至800m 1000m高程這一特殊因素組合引起了右岸巖體沿原有的斷裂(裂隙)張開,使地下水等風化營力能夠到達坡體較深部位,經過長期的風化卸荷作用,形成了右岸復雜巖體。Because during the sedimentation of the flood plain - estuary fades, the conditions of sea level rising, tidal regime, sediment supply and accommodation space were suitable for the development of a tidal ridge system, the sand lenses associated with this facies may represent tidal ridge formation in the incised valley
在河漫灘河口灣相沉積期問,由於海平面上升、潮流體系、沉積物供給和可容空間條件適合一個潮流沙脊體系的發育,其中的砂質透鏡體可能代表了下切河谷內發育的潮流沙脊。Since the last glaciation, with variations in sea level, the development of incised valleys in the hangzhou bay area underwent three stages : 1 ) deep - cutting stage ; 2 ) rapid - filling stage ; and 3 ) rapid - burial stage
末次冰期以來,隨著海平面變化,杭州灣地區下切河谷演化經歷了深切、快速充填和埋藏三個階段。The fall of global sea level during the last glacial maximum enhanced the fluvial gradient and river cutting, resulting in the formation of the large - scale qiantangjiang river and taihu incised valleys which were subsequently filled and rapidly buried in the post - glacial period, with the paleointerfluve being exposed to air on both flanks of the incised valleys
末次冰盛期,海平面下降的幅度大,增加了河流梯度、加強了下切作用,形成了錢塘江和太湖下切河谷,隨后在冰後期被充填和埋藏,下切河谷的兩側為暴露地表的古河間地。All commercial biogenic gas is stored in the flood plain - estuary sand lenses of the incised of the incised valleys
