【背景资料】

某河道治理工程包括新建泵站、新建堤防工程。本工程采用一次拦断河床围堰导流,上下游围堰采用均质土围堰。该工程地面高程30.00m,泵站主体工程设计建基面高程22.90m。
本工程混凝土采用泵送,现场布置有混凝土拌合系统、钢筋加工厂、木工厂、油库、塔吊、办公生活区、地磅等临时设施。根据有利生产、方便生活、易于管理、安全可靠、成本最低的原则,进行施工现场布置,平面布置示意图见图5-1。


施工中发生如下事件:
事件一:基坑初期排水过程中,上游来水致使河道水位上升,上游围堰基坑侧发生滑坡。
事件二:施工单位土方开挖采用反铲挖掘机一次性开挖到22.90m高程。
事件三:启闭机平台简支梁断面示意图见图5-2,梁长6m,保护层25mm,因该工程箍筋中ф8钢筋备量不足,拟采用中ф6或 6钢筋代换,ф6抗拉强度按210MPa, 6抗拉强度按310MPa计算。

事件四:新建堤防迎水面采用混凝土预制块护坡。根据《水利水电建设工程验收规程》(SL223--2008),堤防工程竣工验收前,检测单位对混凝土预制块护坡质量进行抽检。

【不定项选择题】

Emerging in the late Sixties and reaching a peak in the Seventies, Land Art was one of a range of new forms, including Body Art, Performance Art, Action Art and Installation Art, which pushed art beyond the traditional confines of the studio and gallery. Rather than portraying landscape, land artists used the physical substance of the land itself as their medium.

The message of this survey of the British land art--the most comprehensive to date--is that the British variant, typified by Richard Longs piece, was not only more domestically scaled, but a lot quirkier than its American counterpart. Indeed, while you might assume that an exhibition of Land Art would consist only of records of works rather than the works themselves, Longs photograph of his work is the work. Since his action is in the past, the photograph is its sole embodiment.

That might seem rather an obscure point, but it sets the tone for an exhibition that contains a lot of black-and-white photographs and relatively few natural objects.

Long is Britains best-known Land Artist and his Stone Circle, a perfect ring of purplish rocks from Portishead beach laid out on the gallery floor, represents the elegant, rarefied side of the form. The Boyle Family, on the other hand, stand for its dirty, urban aspect. Comprising artists Mark Boyle and Joan Hills and their children, they recreated random sections of the British landscape on gallery walls. Their Olaf Street Study, a square of brick-strewn waste ground, is one of the few works here to embrace the commonplaceness that characterises most of our experience of the landscape most of the time.

Parks feature, particularly in the earlier works, such as John Hilliards very funny Across the Park, in which a long-haired stroller is variously smiled at by a pretty girl and unwittingly assaulted in a sequence of images that turn out to be different parts of the same photograph.

Generally however British land artists preferred to get away from towns, gravitating towards landscapes that are traditionally considered beautiful such as the Lake District or the Wiltshire Downs. While it probably wasnt apparent at the time, much of this work is permeated by a spirit of romantic escapism that the likes of Wordsworth would have readily understood. Derek Jarmans yellow-tinted film Towards Avebury, a collection of long, mostly still shots of the Wiltshire landscape, evokes a tradition of English landscape painting stretching from Samuel Palmer to Paul Nash.

In the case of Hamish Fulton, you cant help feeling that the Scottish artist has simply found a way of making his love of walking pay. A typical work, such as Seven Days, consists of a single beautiful black-and-white photograph taken on an epic walk, with the mileage and number of days taken listed beneath. British Land Art as shown in this well selected, but relatively modestly scaled exhibition wasnt about imposing on the landscape, more a kind of landscape-orientated light conceptual art created passing through. It had its origins in the great outdoors, but the results were as gallery-bound as the paintings of Turner and Constable.

【背景资料】
某大(2)型水库工程主要由主坝、副坝、溢洪道、放水洞、电站等建筑物组成,其中主坝为混凝土重力坝,最大坝高75m。本工程施工混凝土运输主要采用混凝土泵和塔机;溢洪道和电站上部预制构件采用起重机吊装;放水洞采用光面爆破法施工;电站机组采用厂房内的桁车安装。在施工过程中发生下列事件:
事件1:为加强工程施工质量与安全控制,项目法人组织制定了应急救援预案,组织成立了质量与安全事故应急处置指挥部,施工单位项目经理人为指挥,项目监理部、设计代表处的安全分管人员为副指挥。
事件2:为避免主坝在施工过程中产生贯穿性裂缝,施工单位采取了减少混凝土的发热量、降低混凝土的入仓温度、加速混凝土散热等多项温控措施。
事件3:在溢洪道上部预制构件安装过程中,由于设备故障,起重机吊装的预制件突然坠落,致1人死亡、2人重伤、1人轻伤。事故发生后,施工单位项目经理立即向项目法人报告。在事故调查中发现,起重机操作人员没有相应的资格证书。

2011年11月20日4时,A铁矿-100m平巷盲竖井的罐笼在提升矿石时发生卡罐故障,罐笼被撞破损后卡在离井口2.5m处。当班绞车工甲随即升井向值班矿长乙和维修工丙报告,乙和丙下井检修。丙在没有采取任何防护措施的情况下3次对罐笼角、井筒护架(井筒为木支架)进行切割与焊接,切割下的高温金属残块及焊渣掉落在井壁充填护帮的荆笆上。
当日8时10分,甲在绞车房发现提升罐笼的钢丝绳异动,前往井口观察,发现盲竖井内起火,当即返回绞车房,关闭向井下送电的电源开关,并立即升井向乙和丙报告。随后甲和丙一起下井,到达-100m平巷时烟雾很大,能见度不足5m。甲和丙前行到达离起火盲竖井约300m处,无法继续前行,遂返回地面向乙汇报。乙立即报警,请矿山救护队救援,并启动A铁矿应急救援预案。
事故发生时,井下被困人员共122人,其中52人被矿山救护队救出,70人遇难。遇难人员中包括周边4座铁矿的61名井下作业人员。
事故调查发现,A铁矿与周边的4座铁矿越界开采,井下巷道及未经处理的采空区相互贯通。各矿均未形成独立的机械通风系统,且安全出口等标志、标识不符合安全规定
事故调查组确认,该起事故的经济损失包括:人身伤亡后所支出的费用9523万元,善后处理费用3052万元,财产损失1850万元,停产损失580万元,处理环境污染费用5万元等。
