中文摘要
本設(shè)計(jì)由兩部分內(nèi)容組成：第一部分是長(zhǎng)沙是某輕工商業(yè)樓基坑支護(hù)；第二部分是武廣客運(yùn)專(zhuān)線(xiàn)路基工點(diǎn)設(shè)計(jì)。
土釘墻設(shè)計(jì)中，由于工程現(xiàn)場(chǎng)下部土層較好，通過(guò)朗肯主動(dòng)土壓力計(jì)算確定只需在上層填土部分進(jìn)行土釘墻支護(hù)。計(jì)算出土釘使用狀態(tài)下的土體側(cè)壓力，并由此進(jìn)行土釘墻參數(shù)設(shè)計(jì)，最后對(duì)土釘墻的局部穩(wěn)定性、內(nèi)部整體穩(wěn)定性和外部整體穩(wěn)定性進(jìn)行了驗(yàn)算。土釘墻內(nèi)部穩(wěn)定性驗(yàn)算較為復(fù)雜，本設(shè)計(jì)采用了簡(jiǎn)化算法，即把最危險(xiǎn)滑裂面簡(jiǎn)化成了平面。
武廣客運(yùn)專(zhuān)線(xiàn)路基工點(diǎn)設(shè)計(jì)中，由于路基邊坡不是很穩(wěn)定，需要進(jìn)行防護(hù)，本設(shè)計(jì)中采用的是漿砌片石骨架的加固措施；而由于路基下部土層不是很好，通過(guò)計(jì)算確定要進(jìn)行粉噴樁處理。并計(jì)算出粉噴樁處理前后的地基沉降，由此對(duì)下臥層的穩(wěn)定性進(jìn)行驗(yàn)算。
關(guān)鍵詞：基坑；土釘墻；強(qiáng)度；穩(wěn)定性；路基；排水；沉降；粉噴樁；邊坡穩(wěn)定
Abstract
This design consists of two parts: the first part is about the design of soil-nail wall for the foundation pit supporting of the commercial Building of Light Industry Bureau in Hunan；and the second part is about the design of Wuhan-Guangzhou high-speed railway roadbed construction site design.
In the design of the soil-nail wall, according to the Rankine active earth pressure,  the conclusion was got that only the upper filled soil needed supporting because of the good conditions of the lower soil.The lateral earth pressure considering the soil nails was worked out, according to which the soil-nail wall was designed. Finally the local stability, interior stability and external stability of the soil-nail wal were checked. Because it was complicated to check the interior stability, the simplified method was used in the design, which thought of the most dangerous sliding surface as a plane.
In the second design,because of the subgrade is not stable ,and needed the protection, this design is used in the skeleton made of mortar and stones to the reinforcement measures;And due to the lower soil of the subgrade is not very good,confirmed by conputing the decision to treat with DJM. And calculated the settlement of the foundation before and after treatment with DJM, this Checking the stability of the underlying stratum.

Keywords: Foundation pit; Soil-nail wall; Strength; Stability; Soft soil subgrade; Drainage; Subsidence; DJM; Slope stability.
