【文章內(nèi)容簡(jiǎn)介】 ctive earth pressure under the action of horizontal displacement of the outward, caused the wall flare. Construction to plete the back wall of the lateral soil pressure is greater than the inside of the still earth pressure, but the difference between the initial reduce subgrade filling. Completed the earth pressure and back wall panel, the minimum level of consistent deformation results. 各斷面在施工期間基底豎向應(yīng)力隨填土高度增長(zhǎng)的分布曲線以及竣工后各時(shí)間的分布如圖2～3所示。 Each section during the construction of basement vertical distribution curve of stress with the filling height growth, and each time after the pletion of the distribution of as shown in figure 2 ~ 3. （1）隨著填土高度的增大，基底豎向土壓力不斷增大，應(yīng)力增長(zhǎng)速率基本相當(dāng)。 (1) with the increase of filling soil height, basal vertical soil pressure increasing, the stress growth rate. ?。?）竣工后的基底豎向應(yīng)力隨時(shí)間基本呈下降的趨勢(shì)。這是由于在加筋土擋墻的自重荷載作用下復(fù)合地基發(fā)生沉降。有柔性土工格柵設(shè)置在土中會(huì)產(chǎn)生 薄膜或網(wǎng)兜效應(yīng)，土工格柵對(duì)土體形成托舉力，從而改變了豎向應(yīng)力分布，土體自重作用在基底上的豎向土壓力降低。 (2) after the pletion of basement vertical stress basic present decreasing trend with time. This is because the reinforced soil retaining wall under the gravity loads of posite foundation settlement. Flexible geogrid is set in the soil will produce film or net effect, the geogrid on soil formation lift, which changes the vertical stress distribution, the weight of soil on the base of the vertical earth pressure is reduced. ?。?）由于深層水泥攪拌樁復(fù)合地基的樁土應(yīng)力比大于擠密砂礫樁復(fù)合地基的樁土應(yīng)力比，使得深層水泥攪拌樁復(fù)合地基中不同部位的豎向應(yīng)力不均勻性較大。由于加筋土體與非加筋土體和墻面之間的相互作用，豎向土壓力沿筋長(zhǎng)呈曲線分布，而設(shè)計(jì)中的豎向土壓力分布沒有考慮這種因素?！ ?墻背側(cè)向土壓力(3) because of the deep cement mixing pile posite foundation of pile soil stress ratio is greater than the paction pile soil stress ratio of gravel pile posite foundation, makes the deep cement mixing pile posite foundation in different parts of the vertical stress nonuniformity is bigger. Because the reinforced body and the interaction between the reinforced soil mass and metope, the vertical earth pressure distribution along the reinforcement length is curve, and the design of the vertical earth pressure distribution does not take into account this factor. back wall late
