This paper developed a micro angular rate gyro based on micro piezoelectric ceramic rod structure instead of the sensitive double - deck structure as well as piezoelectric ceramic strain foils , and designed a phase - sensitive detection circuit 摘要研制了基于微型壓電陶瓷棒結(jié)構(gòu)代替雙敏感梁結(jié)構(gòu)及壓電陶瓷片的微型角速率陀螺,并設(shè)計了相敏檢波電路。
The dewater calculation result of the south anchor of runyang yangtze river highway bridge ' s shows that the double deck structure model provide a new method to the non linear coupling calculation of deep foundation pit dewater and settlement , forecast and control the distortion of the soil in the pit , engineering construction and design 潤揚(yáng)長江公路大橋南錨基坑工程降水計算表明,雙層結(jié)構(gòu)模型為深基坑降水與沉降的非線性耦合計算,基坑土體變形預(yù)測、控制,工程施工和設(shè)計提供了新的計算分析途經(jīng)。
In view of geological and hydro - geological situations of the south anchor runyang yangtze river highway bridge , the paper bring forward mathematical model and calculation method of double deck structure groundwater , which can be used to lively calculate every layer ' s water table , so that we can realize every layer ' s settlement calculation and control ; establish the inter relationship between non - linear physical - mechanics parameter and hydro - geological parameter , objectively describe the non - linear change process of the porosity , hydraulic conductivity , specific storativity in the process of soil dewater and concretion 針對潤揚(yáng)長江公路大橋南錨場地地質(zhì)、水文地質(zhì)條件提出了雙層結(jié)構(gòu)地下水運(yùn)動的數(shù)學(xué)模型和計算方法,該方法可以實時計算出各分層的地下水位,實現(xiàn)了各分層沉降計算與控制研究;建立了土層非線性物理力學(xué)參數(shù)與水文地質(zhì)參數(shù)之間的內(nèi)在聯(lián)系,客觀地描述土層降水? ?固結(jié)過程中孔隙度、滲透系數(shù)和貯水率等參數(shù)非線性變化過程。
