Friday marks the 40th anniversary of one of the biggest, most expensive, most destructive social policy experiments in American history: The war on drugs. On the morning of June 17, 1971, President Richard Nixon, speaking from the Briefing Room of the White House, declared: "America’s public enemy No. 1 in the United States is drug abuse. In order to fight and defeat this enemy, it is necessary to wage a new, all-out offensive. I have asked the Congress to provide the legislative authority and the funds to fuel this kind of an offensive. This will be a worldwide offensive dealing with the problems of sources of supply, as well as Americans who may be stationed abroad, wherever they are in the world. "

So began a war that has waxed and waned, ,sputtered and sprinted, until it became an unmitigated disaster, an abomination of justice and a self-perpetuating, trillion-dollar economy of wasted human capital, ruined lives and decimated communities. Since 1971, more than 40 million arrests have been conducted for drug-related offenses. And no group has been more targeted and suffered more damage than the black community. As the American Civil Liberties Union pointed out last week, "The racial disparities are staggering: despite the fact that whites engage in drug offenses at a higher rate than African-Americans, African-Americans are incarcerated for drug offenses at a rate that is: 10 times greater than that of whites. "

An effort meant to save us from a form of moral decay became its own insidious brand of moral perversion-turning people who should have been patients into prisoners, criminalizing victimless behavior, targeting those whose first offense was entering the world wrapped in the wrong skin. It feeds our overwhelming thirst for punishment.

Last week, the Report of the Global Commission on Drug Policy, a 19-member commission that included Kofi Annan, a former U. N. secretary general, declared that: "The global war on drugs has failed, with devastating consequences for individuals and societies around the world. Fifty years after the initiation of the U.N. Single Convention on Narcotic Drugs, and 40 years after President Nixon launched the U. S. government’s war on drugs, fundamental reforms in national and global drug control policies are urgently needed. "

The White House immediately shot back: no dice. The Obama administration presented a collection of statistics that compared current drug use and demand with the peak of the late 1970s, although a direct correlation between those declines and the drug war are highly debatable. In doing so, it completely sidestepped the human, economic and societal toll of the mass imprisonment of millions of Americans, many for simple possession.

No need to put a human face on 40 years of folly when you can wrap up its inefficacy in a patchwork quilt of self-serving statistics.

某水库枢纽工程由大坝及泄水闸等组成。大坝为壤土均质坝，最大坝高15.5m，坝长1135m。该大坝施工承包商首先根据设计要求就近选择某一料场，该料场土料粘粒含量较高，含水量较适中。在施工过程中，料场土料含水量因天气等各种原因发生变化，比施工最优含水量偏高，承包商及时地采取了一些措施，使其满足上坝要求。坝面作业共安排了A、B、C三个工作班组进行填筑碾压施工。在统计一个分部工程质量检测结果时，发现在90个检测点中，有7个点不合格。其中检测A班组30个点，有2个不合格点；检测B班组30个点，有3个不合格点；检测C班组30个点，有2个不合格点。
问题：

料场含水量偏高，为满足上坝要求，此时可采取哪些措施
