The basement uplift , the platform shallowening and the marine regression have close relations with the indosinian movement 古地理演化是構造運動的直觀響應,中國南方三疊紀的地殼抬升、臺地淺灘化、海水退出與印支運動密切相關。
The authors hold that the joint actions of numerous factors such as the upper mantle uplifted zone ( the mantle thinned zone of lithosphere ) , the upper mantle anomalous area ( relatively low - velocity area ) , the uplifted zone of intracrustal high - conductivity layer , the deep fault ( shear zone of lithosphere ) , the margin of the crust - upper mantle uneven masses , the basement uplifted area reflected by gravity high , the magmatic belt and tectonic intersection reflected by skipped magnetic field , control the distribution of auriferous skarn deposits and copper ( associated with gold ) skarn deposits 作者認為,上地幔隆起帶(巖石圈地幔減薄帶) 、上地幔異常區(qū)(相對低速區(qū)) 、殼內高導層隆起帶、深斷裂(巖石圈剪切帶) 、地殼上地幔不均勻性塊體的邊緣、重力高反映的基底隆起區(qū)、跳躍磁場反映的巖漿巖帶和構造交匯處等諸多因素的共同作用控制著含金夕卡巖礦床和銅伴生金夕卡巖礦床的分布。
This paper discusses the basic principle and method of the design of the retaining structure with account into deformation controlling by analyzing the relationship between horizontal displacement , vertical subsidence , and basement uplift , by studying the mechanism of the deformation on retaining structure and the influencing factors . the author also provides a method for predicting the displacement of retaining structures by means of neural network 本文在總結深基坑工程設計與施工實踐的基礎上,提出了基坑支護設計方案優(yōu)選方法,以變形控制為主對基坑支護設計方法進行了探討,分析基坑水平位移、垂直沉降與基底隆起的有機聯系,總結分析了影響圍護結構變形的影響因素,闡述了變形控制設計的基本原理與主要內容。
