double stratum
解釋
雙層-
The first power station of jinping mountain lies in the west section of the yanglongjiang river from santan to shoupagou gully, with a double - curved arch dam of 305 - meter height and a normal water storage of 1880metres. the exposed strata of the damsite are marbles and arenaceous rocks of triassic and solution fissures have been developed in the marbles of the left - bank ' s dam abutment, and they have become a stratum of strong leakage. as a result, it has been an important problem for the dam foundation to stop leakage
錦屏一級電站位於西雅礱江的三灘至手爬溝河段，壩型為305米高雙曲拱壩，正常蓄水位標高1880米。壩址區出露的地層為三疊系雜谷腦組二段大理巖和三疊系雜谷腦組三段的砂板巖。在勘探過程中，發現左岸壩肩大理巖體中的構造裂隙和溶蝕裂隙發育，且成為強滲透地層，為此壩基的防滲成為重要問題。 -
This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time
該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。 -
Secondly, analytical solution is developed for one - dimensional non - homogeneous consolidation of one - layer soil and double - layered soil respectively based on the assumption that the modulus of compressibility of soil varying linearly along depth. furthermore, the semi - analytical solution for one - dimensional consolidation problem of layered non - homogeneous soft clay stratum is presented and programmed. by using the analytical and semi - analytical solutions, the one - dimensional non - homogeneous consolidation behavior of one - layer soil and that of multi - layered soil are investigated in detail
其次，分別得到了土體壓縮模量隨深度線性變化的單層和雙層非均質地基一維固結解析解，以及滲透系數和壓縮系數隨深度任意變化的成層非均質地基一維固結半解析解及其計算程序，並以滲透系數和壓縮系數是深度的多項式函數的非均質地基為例對單層、多層非均質地基的一維固結性狀進行了詳細研究。
