中文拼音 [tòushuǐdetǔ]
透水底土
英文
pervious subsoil-
In the end, this paper suggests that, the anti - inrushing stability of confined water foundation pit in soft soil area should be analyzed from perviousness and inrushing mechanism of soil at the bottom of the pit
最後分析指出，軟土地區承壓水基坑抗突涌穩定分析，應從坑底土透水性和土體發生突涌破壞的機理著手。A brief introduction is given to the treatment of the zeya dam foundation, principles of seepage control and design of the concrete face rockfill dam of the zeya reservoir. as for the excavation of the sand - gravel zones, except the toe slab and its 1 / 9 bottom width down stream, the alluvial layers are excavated to the micro - weathered rocks, while the other sections remain unexcavated. regarding to the treatment of the fracture zones, concrete filling is used for the toe slabs and semi - permeable materials are used for other section. according to the construction characteristics, a filter is placed in the down stream embankment foot. to improve the integrity of the dam foundation and anti - seepage capability consolidation grouting and curtain grouting are adopted. as a result safety, economic benefit, convenience in construction and good performace are achieved
簡要論述澤雅水庫面板堆石壩壩基處理和防滲的原則及設計要點.趾板基礎和堆石體各區砂礫石基礎開挖，除趾板與其下游1 / 9底寬范圍以及壩腳挖除沖積層至弱風化（局部微風化）基巖外，其餘部分均予以保留.斷層破碎帶處理，趾板部位採用混凝土塞，其它部位採用半透水料置換，並根據本工程特點在下游壩腳加設了反濾層.為提高壩基的整體性和防滲性能，對趾板進行了固結和帷幕灌漿.達到了安全、經濟、便於施工的目的，運行情況良好，可為面板堆石壩的設計和研究提供參考與借鑒For impervious layer, the anti - inrushing stability of the pit is analyzed from the plastic damage of soil, but for semipervious layer, the anti - inrushing stability of the pit is analyzed from the seepage damage of soil
坑底為不透水層土時，應從土體發生突涌塑性破壞的角度進行分析；坑底為弱透水層土時，應從土體發生突涌滲透破壞的角度進行分析。By reducing the permeability of soil at the bottom of pit and selecting optimal dewatering depth, the settlement of ground surface can be well controlled
採用降低坑底土層滲透性的措施和選擇最佳的降水深度能有效地控制坑外地表的沉降。The spokesman said issues in relation to tunnel construction, including loss and contamination of ground water, subsidence and blow - out, will be addressed by way of the use of an earth pressure balance tunnel boring machine which has been proven to be very successful in the construction of one of the most difficult sections of the west rail, the tsing tsuen tunnel
九鐵發言人指出，透過使用土壓平衡隧道鉆挖機，可以解決各種建造隧道的問題，如地下水流失和污染、土地沉降及泥漿從地底湧出等。西鐵即採用了相同的鉆挖機完成其中一項艱鉅的工程Fall the organic fertilizer into container, sprinkle the soil until the water can permeate through the bottom of the container
將培養土倒入容器，再用細水噴灑土層至容器底部透水為止。分享友人
