中文拼音 [xièhébǎn]
卸荷板
英文
relieving floor-
After excavation, there are concentration phenomenon of stress at the corner or the shiplock room, and the tension zone lies in half of the middle part as well as the part of the two slopes to the lower part of the upright wall. finally the analysis results are compared with site monitoring data in period of construction as well as the feedback reports, the result of all comes to meet with each other very well
開挖完成後，在閘室拐角處存在不同程度的應力集中現象，中隔墩上部1 2的巖體及南北邊坡至直立墻頂部平臺以下的部分巖體為拉應力區。在兩側邊坡及邊墻的塑性區出現在損傷區和部分卸荷影響區內，中隔墩大部分區域的巖體都進入了塑性狀態，閘室底板處的塑性區基本上與損傷區一致。With the help of this program, this paper does research on the moved backwards of the slide surface, lengthening the anchor section, the soil nail ' s total force, gets conclusion about relations between the soil nail ' s length and the slope ' s grade, height, soil ' s mechanical parameter ; relations between soil nail ' s total force and coulomb soil pressure. with the help of the large multiuse finite element program ansys, this paper analyzes the soil nailing in one - step ' s slopes, in two - steps " slopes, puts the emphasis on the axis force ' s distributing along the soil nail at each rows, the effect of both the excavating mode and the original slope figure to the axis force of the soil nail, the one another effect between the upper - step slope and the nether - step slope in the soil nail ' s axis force, gets conclusion about the design of soil nail at the first low, different slope body is the same with different excavating mode, the original slope figure has more effect to some than others because of the slope body, the reasonably design of the step width in two - steps slopes, the two - steps excavating and retaining has more virtue than the one - step ' s. through soil pressure analysis this paper does research on the differences and the links between the coulomb soil pressure theory and the rankin ' s, the vertical pressure at the slope surface when the slope surface is inclined and the retaining wall is rough, the soil pressure ' s distributing behind the panel, gets conclusion about the effect of both the slope body inner stability and the slope surface local stability to the soil pressure
通過分析比較，論證了對數螺旋線型比圓弧形作為邊坡的假設滑裂面具有較多的工程優點，並為此編制了一個採用極限平衡法分析土釘支護的fortran語言程序，以此作工具對滑裂面的后移、土釘錨固段的超長、土釘總力的大小等方面作了研究，得出了有關土釘的長度與邊坡的坡角、坡高、土體力學參數的關系、土釘總力與庫侖土壓力間的關系等結論；採用大型通用有限元數值分析程序ansys分別對採用土釘支護的一階邊坡、二階邊坡進行分析，重點是研究各排土釘的軸力分佈規律、開挖方式及原始邊坡形態對土釘的軸力的影響、上下階邊坡在土釘軸力方面的相互作用，得出了有關第一排土釘的設計問題、不同類型的土體應適用於特定的開挖方式、原始開挖出的邊坡形態對一些類型坡體的邊坡土釘支護有較大的影響而對另外一些影響不大、二階邊坡臺階寬度的合理確定、二階開挖及支護比一階時具有較多的工程優點等結論；通過土壓力分析對朗肯、庫侖兩種經典土壓力理論的區別與聯系、坡面傾斜及墻背有摩擦時的坡面豎向應力分佈、面板背土壓力的分佈形態作了研究，得出了邊坡支擋土壓力受坡體內部穩定與坡面局部穩定兩個方面的影響、土釘支護面板背土體中卸荷拱的存在對面板受力有利等結論。The exam validates existence of the unloading arch. the difference between the result and the classic soil stress theory is due to the effect of unloading arch
模型試驗驗證了卸荷拱的存在，也正是由於卸荷拱的作用，導致擋板後土壓力與經典土壓力的差別。Combining the unloading arch theory and parallel walls theory, the paper analyzes stress state of the soil inside the arch and presents a formula in order to calculate the soil stress on the holding sheet
本文結合卸荷拱理論和平行墻理論，對卸荷拱內土體應力狀態進行了分析，推導出可用於擋板土壓力的計算公式。分享友人
