案例二[背景资料]某建筑工程建筑面积205000m2，混凝土现浇结构，筏板式基础，地下三层，地上十二层，基础埋深12.4m，该项工程位于繁华市区，施工场地狭小。工程所在地区地势北高南低，地下水流从北向南。施工单位的降水方案计划在基坑南边布置单排轻型井点。基坑开挖到设计标高后，施工单位和监理单位对基坑进行验槽，并对基底进行了钎探，发现地基东南角有约350m2软土区，监理工程师随即指令施工单位进行换填处理。工程主体结构施工时，二层现浇钢筋混凝土阳台在拆模时沿阳台根部发生断裂，经检查发现是由于施工人员将受力主筋位置布置错误所造成的。事故发生后，业主立即组织了质量大检查，发现一层大厅粱柱节点处有露筋；已绑扎完成的楼板钢筋位置与设计图纸不符；施工人员对钢筋绑扎规范要求不清楚。工程进入外墙面装修阶段后，施工单位按原设计完成了965m2的外墙贴面砖工作，业主认为原设计贴面砖与周边环境不协调，要求更换为大理石贴面，施工单位按业主要求进行了更换。[问题] 发现基坑基底软土后应按什么工作程序进行基底处理？
Can the Internet help patients jump the line at the doctor’s office The Silicon Valley Employers Forum, a sophisticated group of technology companies, is launching a pilot program to test online "virtual visits" between doctors at three big local medical groups and about 6 000 employees and their families. The six employers taking part in the Silicon Valley initiative, including heavy hitters such as Oracle and Cisco Systems, hope that online visits will mean employees won’t have to skip work to tend to minor ailments or to follow up on chronic conditions. "With our long commutes and traffic, driving 40 miles to your doctor in your hometown can be a big chunk of time, "says Cindy Conway, benefits director at Cadence Design Systems, one of the participating companies. Doctors aren’t clamoring to chat with patients online for free; they spend enough unpaid time on the phone. Only 1 in 5 has ever e-mailed a patient, and just 9 percent are interested in doing so, according to the research firm Cyber Dialogue. "We are not stupid," says Stifling Somers, executive director of the Silicon Valley employers group. "Doctors getting paid is a critical piece in getting this to work." In the pilot program, physicians will get $20 per online consultation, about what they get for a simple office visit. Doctors also fear they’ll be swamped by rambling e-mails that tell everything but what’s needed to make a diagnosis. So the new program will use technology supplied by Healinx, an Alameda, Calif-based star-up. Healinx’s "Smart Symptom Wizard" questions patients and turns answers into a succinct message. The company has online dialogues for 60 common conditions. The doctor can then diagnose the problem and outline a treatment plan, which could include e-mailing a prescription or a face-to-face visit. Can e-mail replace the doctor’s office Many conditions, such as persistent cough, require a stethoscope to discover what’s wrong and to avoid a malpractice suit. Even Larry Bonham, head of one of the doctor’s groups in the pilot, believes the virtual doctor’s visits offer a "very narrow" sliver of service between phone calls to an advice nurse and a visit to the clinic. The pilot program, set to end in nine months, also hopes to determine whether online visits will boost worker productivity enough to offset the cost of the service. So far, the Internet’s record in the health field has been underwhelming. The experiment is "a huge roll of the dice for Healinx", notes Michael Barrett, an analyst at Internet consulting firm Forester Research. If the "Web visits" succeed, expect some HMOs (Health Maintenance Organizations) to pay for online visits. If doctors, employers, and patients aren’t satisfied, figure on one more E health star-up to stand down. Of the following people, who are not involved in the program
Interest is steadily spreading from a minority of enthusiasts in developing renewable sources of energy--wind, wave and solar power, tidal and geothermal energy. Additional support for them has come with a proposal to explore the untapped sources of hydro-electric power in Scotland. The details are provided by Mr. William Manser in a study provided for an expert committee to look at the developments possible for hydro-electric sites and, more important, for means of financing them. There is a clear industrial connection in Mr. Manser’s study because it was done for the Federation of Civil Engineering Contractors; hydro-electric schemes, by definition, have a large civil engineering component in them. Mr. Manser estimates that wind power could theoretically provide more than 7 percent of electricity supply in the United Kingdom, provided suitable sites for generators could be found. However, the practical viability of wind power generation is not likely to be understood until 1990. Other developments using renewable energy sources are also at an early stage as far as their commercial possibilities are concerned, he believe. The best developed and most suitable form of renewable energy is, in his view, hydro power. The technology has been developed over centuries and is still progressing. At present it is the cheapest form of electricity generation. Mr. Manser studied past surveys of the north of Scotland and identified several as suitable for hydro-electric generation. Those are in the remote areas, usually of great natural beauty. But Mr. Manser says a well-designed dam can be impressive in itself. It is also possible to make installation as unobtrusive as possible, to the point of burying parts of them. Hydro generation involves no water pollution, smoke creation or unsightly stocking-out yards. The main trouble, which appears from his report, is financing an undertaking which has a heavy initial capital cost, and very low running costs. However, Mr. Manser does not see that as an unfamiliar position for the electricity industry. He cites the proposed construction of the new nuclear power station at Sizewell in Suffolk, which will have a high initial capital cost. The argument at Sizewell that the reason for the expenditure is that the capital will provide a benefit in lower costs and higher returns in the long-term, applies equally to hydro-electric generation. In Mr. Manser’s opinion, the main stumbling block to the development of hydro-electric power is the
