【摘要】：隨著地下復(fù)合停車場、地下醫(yī)院、地下商場、城市地鐵、人防工程、高層建筑等工程的不斷發(fā)展,基坑的埋置深度越來越大,基坑邊坡的穩(wěn)定逐漸成為不可忽視的問題,各類深基坑工程的支護(hù)隨之大量涌現(xiàn)。深基坑工程的基坑支護(hù)結(jié)構(gòu)雖然不是永久性結(jié)構(gòu),投資大不免會(huì)造成浪費(fèi),但基坑的支護(hù)不穩(wěn)定,將勢必造成工程質(zhì)量事故的發(fā)生。為了確保穩(wěn)定性,建筑物的基礎(chǔ)都必須滿足地下埋深嵌固的要求,所以無論是基坑的支護(hù)還是施工方案都面臨著廣度和深度的挑戰(zhàn)。研究深基坑支護(hù)設(shè)計(jì)和施工方案也就具有了重要的科學(xué)意義和應(yīng)用價(jià)值。論文通過對(duì)懷特商城二期工程深基坑周圍環(huán)境、開挖深度、地下水位高低、基坑側(cè)壁安全、邊坡土質(zhì)情況的調(diào)查和分析,確定該深基坑的支護(hù)方案為土釘支護(hù)加多排樁的樁錨支護(hù)形式,然后選取設(shè)計(jì)參數(shù)并對(duì)支護(hù)方案確定的支護(hù)結(jié)構(gòu)進(jìn)行穩(wěn)定性驗(yàn)算。為了保證基坑工程的順利進(jìn)行及基坑安全,選擇了合理的施工方案,并對(duì)基坑支護(hù)的施工過程進(jìn)行管理,利用施工監(jiān)測手段,加以現(xiàn)場文明施工措施以及質(zhì)量保證體系,確保了該深基坑工程施工的順利進(jìn)行。為同類深基坑支護(hù)工程的設(shè)計(jì)和施工提供了參考、借鑒。
[Abstract]:With the continuous development of underground compound parking lot, underground hospital, underground shopping mall, city subway, civil air defense engineering, high-rise building and so on, the buried depth of foundation pit is increasing, and the stability of foundation pit slope is becoming a problem that can not be ignored. The supporting structure of deep foundation pit works is not permanent structure, and the investment will inevitably cause waste, but the foundation pit support is unstable. In order to ensure the stability, the foundation of the building must meet the requirements of the deep embedded underground. Therefore, both the foundation pit support and the construction plan are facing the challenge of breadth and depth. It is also of great scientific significance and application value to study the design and construction scheme of deep foundation pit support. The surrounding environment of the deep foundation pit of the second phase project, The depth of excavation, the level of groundwater level, the safety of side wall of foundation pit, and the investigation and analysis of the soil quality of the slope are investigated and analyzed. It is determined that the support scheme of the deep foundation pit is the form of pile anchor supporting with soil nailing and multi-row piles. Then the design parameters are selected and the stability of the supporting structure determined by the supporting scheme is checked. In order to ensure the smooth progress of foundation pit engineering and the safety of foundation pit, a reasonable construction scheme is selected, and the construction process of foundation pit support is managed. By means of construction monitoring, the site civilized construction measures and quality assurance system are used to ensure the smooth construction of the deep foundation pit, which provides a reference for the design and construction of the similar deep foundation pit supporting engineering.
